USR1101

Preliminary

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.

SOP-8

Adjustable over-current protection (OCP) monitors the voltage

drop across the R_DS(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 frequency

* Internal soft-start

* Over-current fault monitor on MOSFET, no current sense

resistor required

* RoHS compliant and 100% lead (Pb)-free
