MP2176

6V, 6A, High-Efficiency, Synchronous Step-Down Converter

New

Datasheet

Description

The MP2176 is a monolithic, step-down, switch-mode converter with internal power MOSFETs that can achieve up to 6A of continuous output current from a 1.5V to 6V input voltage with excellent load and line regulation. The output voltage can be regulated as low as 0.61V.

Constant-on-time (COT) control provides fast transient response and eases loop stabilization. Fault condition protections include cycle-by-cycle current limiting and thermal shutdown.

The operating frequency is programmed by an external resistor and is compensated for variations in V_IN.

Full protection features, including over-current protection (OCP), short-circuit protection (SCP), over-voltage protection (OVP), under-voltage protection (UVP), and over-temperature protection (OTP), are provided by internal comparators.

The MP2176 requires a minimal number of readily available, standard, external components and is available in a QFN-14 (3mmx4mm) package.

Evaluation Tools

EV2176-L-00A Evaluation Kit High-Efficiency, 6A, 6V, Synchronous Step-Down Converter Evaluation Board

The EV2176-L-00A is an evaluation board for the MP2176GL, a high-efficiency, monolithic, synchronous step-down converter. The evaluation board can deliver 6A of continuous load current from a 3V to 6V input with excellent load and line regulation. Constant-on-time (COT) control mode provides fast transient response and eases loop stabilization.

The evaluation board can be turned on or shut down via a remote on/off input that is referenced to ground. This input is compatible with popular logic devices.
