The EV28115DQ-01C is an evaluation board for the MP28115, a monolithic synchronous buck regulator.

The MP28115 delivers 4A continuous load current over an operating input voltage 2.7V to 6.0V. The output is adjustable over a range of 0.8V to 0.9xVIN by means of an external resistor from FB pin to ground.

The current mode control used in MP28115 provides fast transient response and cycle-by-cycle current limiting. The EV board will go into hiccup mode to protect against over current/short circuit.

This EV 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.

This EV board also has power good indicator. The output of POK is pulled to ground when output voltage is under or over 10% of its setting voltage.
