The EV28310-C-00A is an evaluation board designed to demonstrate the capabilities of the MP28310, a monolithic power management unit that integrates a 300mA, high-efficiency, step-down switching converter and a 100mA low-dropout (LDO) regulator. The sub-mA quiescent current (I_Q) provides extremely high efficiency when the load current is low (down to the µA range). With a maximum 5.5V input voltage (V_IN), the MP28310 is ideal for use in battery-powered devices.

Constant-on-time (COT) control provides fast transient response, high light-load efficiency, and allows for minimal capacitance. An additional 100mA LDO regulator provides simple system configuration with a low LDO output voltage ripple.

The MP28310 is available in a small CSP-12 (1.2mmx1.6mm) package.
