The PT16922 is designed to operate as a constant current source for car brake- and tail-light applications using buck topology. A 4-channel output is provided to drive additional LEDs in 12V automotive systems. The maximum output current for each channel is up to 250mA in brake-mode and 15mA in tail light-mode. The current for each mode may be set separately. Changing the operating mode between brake- and tail-light modes may be accomplished thru the use of an external brake signal. The response time in brake-mode is less than 10ms.

The PT16922 uses a heat spreading HTSSOP24 package for improved reliability. The PT16922 also includes multiple protection schemes, including thermal shutdown protection and temperature compensation function, output short protection, input over-voltage protection, and LED open and short protection, in order to maximize the safe operation and reliability of the product.
