EVM3805-QB-01A
6V, 0.6A Synchronous
Step-Down Switcher Evaluation Board
DESCRIPTION
The EVM3805-QB-01A is used for
demonstrating the performance of MPS’s
MPM3805 a low voltage high switching
frequency step-down switcher with built-in
power MOSFETs and power inductor.
MPM3805 provides up to 0.6A 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.
MPM3805 is available in QFN 3.0x2.5x0.9mm
package.
