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

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.
