PFM STEP-DOWN DC-DC

CONTROLLER

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.

There are two user-selectable over-current protection methods

one provides over-current protection by taking advantage of the

RDS(ON) of the P- Channel. The other provides accurate over-current

protection with the use of an external sense resistor. The

cycle-by-cycle current limit threshold can be adjusted with a

external resistor.

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
