Catalyst publishes the smallest size, highest efficiency fractional charge pump

Catalyst again quickly introduced the three-channel CAT3643 and the four-channel CAT3644 Quad-Mode â„¢ fractional charge pump to take LED driver performance to a whole new level. Among them, the CAT3643 Quad-Mode â„¢ charge pump is the smallest and most efficient charge pump in the world. It is packaged in a 2.5mm x 2.5mm XQFN package with a thickness of 0.4mm and is more efficient than an ordinary charge with only three modes Pump increased by 10%. Only two months after the introduction of the groundbreaking Quad-Mode technology that drives six LED drivers, the CAT3636, Catalyst introduces the latest CAT3643, which can drive up to three LEDs. Thanks to the Quad-Mode architecture, the newly released CAT3643 and CAT3644 deliver up to 92% efficiency while saving board space and costs. The CAT3643 is currently the only charge-pump product in the XQFN miniature 2.5mm * 2.5mm, 0.4mm package, compared to the 0.8mm-high, 3mm x 3mm 16-pin TQFN package of traditional triple-mode charge pumps. Catalyst Semiconductor's innovative and patent-pending Quad-Mode charge pump architecture delivers the same high efficiency as inductive LED drivers while avoiding the problems of over-thickness and EMI interference with the inductor. Most current charge pump LED drivers provide three modes of operation based on the ratio of output voltage to input voltage: 1x, 1.5x and 2x. Quad-Mode architecture adds a fourth mode of operation - 1.33x and eliminates the need for additional capacitors, which is a reduction of at least two pins compared to 1.33x the rest of the company, allowing the device to be small and extremely small Pin XQFN package. The 1.33x mode of operation also effectively reduces the input switch current on the battery side, minimizing the system's input noise, which is an important factor in portable devices such as cell phones. In addition, the 1.33x mode of operation allows the output of the boost voltage as small as possible, which greatly reduces the device's useless power consumption and subsequent heat loss. Thanks to the smaller pin count XQFN package and high efficiency, the CAT3643 is the thinnest (only 0.4mm thick), fractional, fractional charge product (65% smaller than conventional products) in the world today. Using Catalyst's single-wire EZDim LED current programming interface with the triple-mode charge pump, the CAT3643 provides the flexibility to control LEDs and achieve brightness control. The EZDim LED current programming interface offers six different current ratio adjustments. Introduced in conjunction with the CAT3643, the CAT3644 is a quad-mode quad-mode chip that can drive up to 4 LEDs with up to 92% efficiency.

High Speed Door Motor And Control Box

Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.

About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.

About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: <16 ㎡; Daily operating time: >2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.

The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.

System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.

Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.

The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.

Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.

Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.

About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
