USR1101 Overview
The UTC USR1101 is a high efficiency synchronous buck PWM controller, with operating at fixed 300kHz frequency, Internal soft-start, frequency pensation 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...
