Description

The A8516 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 currentsinks. The boost converter operates in constant frequency (programmable) current mode control.

The LED sink current is set by an external R_ISET resistor (see chart below). More than one LED sinks can be combined together to achieve even higher current per LED string.

The A8516 operates from a single supply of 8 to24 V. It provides protection against overvoltage, open or shorted LED string, and overtemperature. A dual level cycle-by-cycle current limit function provides soft start and protects against overloads.

Features and Benefits

? Six integrated high current sinks

? Fixed frequency current mode control with integrated gate driver

? 300 kHz to 1 MHz adjustable Boost switching frequency

? Controlled startup using options of Enable, PWM signal, or battery voltage ramp

? Active current sharing between LED strings for ±0.6 accuracy and matching

? No audible MLCC noise during PWM dimming

? Adjustable overvoltage protection (OVP)

? Open or shorted LED string protection

? Overtemperature, cycle-by-cycle current limit, and undervoltage protection

? SOIC 24-pin package for easy single-side PCB manufacturing, or TSSOP 24-pin package with exposed thermal pad for better thermal performance
