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.

4A, 1.5MHz Synchronous Step-Down Converter
The MP28115 is an internally compensated 1.5MHz fixed frequency PWM synchronous step-down regulator. MP28115 operates from a 2.7V to 6V input and generates an adjustable output voltage from 0.8V to 0.9xVIN at up to 4A load current. The MP28115 integrates a 60mO high side switch and a 60mO synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, the MP28115 based solution achieves minimum footprint and component count. Fault condition protection includes Hiccup short-circuit protection, cycle-by-cycle current limiting and thermal shutdown. Other features include frequency synchronization input, internal soft-start and power good output. The MP28115 is available in a small 3x3mm 10-lead QFN package.
