Product Description

The EV2131-G-00A is used for demonstrating the performance of MPS’s MP2131, a low voltage high switching frequency step-down switcher with built in power MOSFETs. MP2131 provides up to 4A highly efficient output with constant-on-time control for fast loop response.

MP2131 is ideal for powering portable equipment that runs from a single cell Lithium-ion (Li+) Battery. The output voltage can be regulated as low as 0.6V.

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.

MP2131 is available in QFN12 (2x2mm) package.

Monolithic IC


IC Details

The MP2131 is a monolithic step-down, switch- mode converter with built-in internal power MOSFETs. It achieves a 4 A continuous output current from a 2.7 V to 5.5 V input voltage with excellent load and line regulation. The MP2131 is ideal for powering portable equipment that run from a single cell lithium-ion (Li+) battery. The output voltage is regulated as low as 0.6 V. The constant-on-time (COT) control scheme provides fast transient response, high light-load efficiency, and eases loop stabilization. Fault condition protection includes cycle?y?ycle current limit and thermal shutdown. The MP2131 requires a minimum number of readily available, standard, external components and is available in an ultra-small QFN-12 (2mm x 2mm) package. The MP2131 is ideal for a wide range of applications including portable instruments, small handheld and battery?owered devices, PDAs, and DVD drives.
