A8507ELPTR-T - Brand New Allegro MicroSystems LED Drivers
-
Description
The A8507ELPTR-T is a multi-output WLED/RGB driver for backlighting LCD monitors and televisions. It integrates a boost controller to drive external MOSFET and six internal current-sinks. The boost converter operates on a constant frequency current mode control.
Specifications and features
- 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
- Available in SOIC 24-pin package for easy single-side PCB manufacturing or TSSOP 24-pin package with exposed thermal pad for better thermal performance
Application Scenarios
Designed specifically for backlighting LCD monitors and televisions, the A8507ELPTR-T is suitable for various electronics and electrical devices that require efficient and reliable LED driver solutions.
