Overview
A multi-output white LED driver for LCD backlighting. It integrates a current-mode boost converter with internal power switch and 8 current sinks. The boost converter can drive up to 96 LEDs with 12 LEDs at 40 mA per string. The LED sinks can also be paralleled together to achieve even higher LED currents, up to 320 mA. It can operate from a single power supply, from 5 to 40 V. If required, it can drive an external P-FET to disconnect the input supply from the system in the event of a fault. It provides protection against output short and overvoltage, open or shorted diode, open or shorted LED pin, and overtemperature. A dual level cycle-by-cycle current limit function provides soft start and protects the internal current switch against high current overloads. It has a synchronization pin that allows PWM switching frequencies to be synchronized in the range of 580 kHz to 2.3 MHz. The device package is a 26-contact, 4 mm×4 mm, 0.75 mm nominal overall height QFN, with exposed pad for enhanced thermal dissipation. It is lead (Pb) free, with 100% matte tin leadframe plating.
Applications
- Industrial LCD displays
