LINEAR INTEGRATED CIRCUIT
5V/12V SYNCHRONOUS BUCK PWM DC-DC CONTROLLER
DESCRIPTION
The UTC USR1101 is a high efficiency synchronous buck PWM controller, with operating at fixed 300kHz frequency, Internal soft-start, frequency compensation networks and integrates all of the control, output adjustment, monitoring and protection functions into a single package.
Adjustable over-current protection (OCP) monitors the voltage drop across the RDS(ON) of the lower MOSFET for synchronous buck PWM DC-DC controller.
FEATURES
* Operating with 5V or 12V supply voltage * Drives all low cost N-channel MOSFETs * PWM control mode * 300kHz fixed frequ...
