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.
