Additional preview pages of the LP8545 datasheet.

The LP8545 is a white LED driver with integrated boost converter.

It has six adjustable current sinks which can be controlled by PWM input or with I2C-compatible serial interface.

The boost converter has adaptive output voltage control based on the LED driver voltages.

which make it possible to detect LED outputs with open or short fault. As well low input voltage and boost over-current conditions are monitored and chip is turned off in case of these events. Thermal de-rating function prevents overheating of the device by reducing backlight brightness when set temperature has been reached. LP8545 is available in National's LLP 24-pin package. Features.
High-voltage DC/DC boost converter with integrated FET.
with four switching frequency.
