MPM3830

6V Input, 3A Module Synchronous Step-down Converter with Integrated Inductor

Datasheet

Description

The MPM3830 is a monolithic step-down switch mode converter with built-in internal power MOSFETs and inductor. The DC-DC module has a small surface mount 3mm x 5mm x 1.6mm QFN package. It achieves 3A continuous output current from a 2.7V to 6V input voltage with excellent load and line regulation. The MPM3830 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. Only input, output capacitors and FB resistors are needed to complete the design. The Constant-On-time (COT) control scheme provides fast transient response, high lightload efficiency and easy loop stabilization. Fault condition protection includes cyclebycycle current limit and thermal shutdown. The MPM3830 requires a minimum number of readily available standard external components and is available in an ultra-small QFN20 (3mmx5mm) package.

The EVM3830-QV-00A is an evaluation board designed to demonstrate the capabilities of the MPM3830, a low-voltage, high switching frequency (f_SW) step-down switcher with built-in power MOSFETs and a power inductor. The MPM3830 provides up to 3A of continuous and highly efficient output with constant-on-time (COT) control for fast loop response.

High power efficiency across a wide load range is achieved by scaling down f_SW at light loads to reduce the switching losses related to COT control. Short-circuit protection (SCP) and thermal shutdown provide reliable, fault-tolerant operation.

The MPM3830 is available in a QFN-20 (3mmx5mm) package.
