A8507ELB Datasheet PDF - Allegro MicroSystems

Description
The A8507 is a multi-output WLED/RGB driver for backlighting LCD monitors and televisions. The A8507 integrates a boost controller to drive external MOSFET and six internal current-sinks. The boost converter is constant frequency current mode converter.

FEATUREs and Benefits
▪Fixed frequency current mode control with integrated gate driver
▪Each individual current sink is capable of 80 mA
▪Adjustable overvoltage protection (OVP)
▪Active current sharing between LED strings for ±0.6% accuracy and matching
▪250 kHz to 1 MHz adjustable switching frequency
▪Open or shorted LED string protection
▪Overtemperature, cycle-by-cycle current limit, and undervoltage protection
▪No audible MLCC noise during PWM dimming
▪No pull-up resistors required for LED modules that use ESD capacitors
▪SOIC 24-pin package for easy single-side PCB manufacturing or TSSOP 24-pin package with exposed thermal pad for better thermal performance
