AT9917 driver equivalent, automotive led driver.
* Switch mode controller for boost, SEPIC & buck converters
* Closed loop control of output current
* High PWM dimming ratio
* Internal 40V linear regulat.
An internal 40V linear regulator powers the IC eliminating the need for a separate power supply for the IC. The IC prov.
The AT9917 is an advanced fixed frequency PWM IC designed to control single-switch, boost, SEPIC, and buck LED drivers in a constant current mode. The controller uses a peak current-mode control scheme (with programmable slope compensation) and inclu.
