RT8106/RT8106A

5V/12V Synchronous Buck PWM DC-DC Controller

RT8106/RT8106A
New

The RT8106/A is a DC/DC synchronous buck PWM controller with embedded driver support up to 12V+12V boot-strapped voltage for high efficiency power driving. The part integrates full functions of voltage regulation, power monitoring and protection into a single small footprint WDFN-10L 3x3 (Exposed Pad) package. The RT8106/A adopts a high-gain voltage mode PWM control for simple application design. An internal 0.8V reference allows the output voltage to be precisely regulated for low voltage requirement. Based on all RT8106/A features, the part provides an optimum compromise between efficiency, total B.O.M. count, and cost.
