DESCRIPTION

The UTC M7085 step-down DC-DC Controller is optimized for use with a power PMOSFET. It utilize a Pulse-Frequency Modulation (PFM) control scheme that implies high efficiency operation at light loads.

FEATURES

* High efficiency 90 and up is possible

* Low dropout operation：100 duty cycle

* Maximum operating frequency > 1MHz

* Two methods of over-current protection

* 4.5V ~ 35V wide input range

* 1.24V ~ VIN adjustable output range
