Product Description

The EV2187-QA-01A evaluation Board is designed to demonstrate the capabilities of MP2187, an internally compensated 1.2MHz dual COT synchronous step-down regulator. The output voltages of the two channels are 1.1V and 1.8V respectively.

The constant-on-time control scheme provides fast transient response and eases loop stabilization. Fault condition protections include cycle-by-cycle current limiting and thermal shutdown.

The MP2187 is available in small 2.2mmx2.6mm QFN16 package and requires only a minimal number of readily available standard external components.

IC Details

The MP2187 is a monolithic, step-down, switch-mode dual converter with internal power MOSFETs. It can achieve up to 3A continuous output current from a 2.5V?o-5.5V input voltage with excellent load and line regulation. The output voltages of two channels are 1.1V and 1.8V respectively. The constant-on-time control scheme provides fast transient response and eases loop stabilization. Fault condition protections include cycle-by-cycle current limiting, input voltage failure indicator and thermal shutdown. The MP2187 is available in small 2.2mmx2.6mm QFN16 package and requires only a minimal number of readily available standard external components. The MP2187 is ideal for a wide range of applications including high-performance DSPs, FPGAs, smart phones, portable instruments, and DVD drivers.
