PFM STEP-DOWN DC-DC CONTROLLER
DESCRIPTION
The UTC M7085 step-down DC-DC Controller is optimized for use with a power P
MOSFET.
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.
