DESCRIPTION

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

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.
