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 VIN.
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 KitGET THIS KIT
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 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 reference to ground. This input is compatible with popular logic devices.
