Designed for automotive and consumer backlit LCD display

Worcester, 亚博棋牌游戏Massachusetts - Allegro MicroSystems introduced a new single input white leds (WLED) drive, designed for automotive and consumer backlit LCD display and the requirement of application, performance and protection design.The AllegroA8513Integration of the current mode boost converter with the internal power switch and a current drawn into the device.This is a suitable for car entertainment information, battery and instrument panel, industrial LCD monitors, portable DVD players, flatbed scanner and LED lighting applications, such as solid and durable solutions.

A8513 4.5 to 40 v single power supply used for operation, in order to meet the startup/shutdown, cold start and load sudden drop requirements.2 MHz step-up converter switching frequency can make the A8513 above an AM radio wavelengths.Fault tag if necessary, can be used as part of the circuit, on the outside of the failure drive P - FET disconnect the input power of the system.The device offers all kinds of protection, including the output short circuit and over voltage, open circuit or short circuit diode, short circuit, open circuit or short circuit of LED pin booster switch or inductors, short circuit ISET resistor and IC over temperature protection.Two stage by wave current limiting function can provide soft start and to prevent the occurrence of high current overload current switch inside.

Allegro A8513 the eMSOP - 10 and 16 eTSSOP - encapsulation.These devices will provide all the oscillator frequency - please contact Allegro for detailed information.
