DESCRIPTION

The

EVM3810-QB-01A

is

used

for

demonstrating the performance of MPS’s

MPM3810 a low voltage high switching

frequency step-down switcher with built-in

power

MOSFETs

and

power

inductor.

MPM3810 provides up to 1.2A peak highly

efficient output with constant-on-time control for

fast loop response.

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. Short

circuit and thermal shutdown provides reliable,

fault-tolerant operation.

MPM3810 is available in QFN 3.0x2.5x0.9mm

package.
