Adaptive COT Control for Ultrafast
Transient Response
Programmable Switching Frequency from
200KHz to 1MHz
Support Pre-Bias Start Up
Programmable Soft-Start Time with Default
3ms
Non-latch OCP, OVP and Thermal
Shutdown
demonstrating the performance of MPS’
MPM3686, a 20A step-down power module
with built-in power MOSFETs and power
inductor.
•
•
•
High power efficiency over a wide load range is
achieved by scaling down the switching
frequency at light load to reduce the switching
related loss by constant on time control. Over-
Current-Protection, Over-Voltage Protection,
•
•
Under-Voltage
shutdown provide reliable operation.
