2A, 6V, 720KHz

Synchronous Buck Converter

The Future of Analog IC Technology

INITIAL RELEASE – SPECIFICATIONS SUBJECT TO CHANGE

DESCRIPTION

FEATURES

The MP2108 is a 2A, 720KHz synchronous

buck converter designed for low voltage

applications requiring high efficiency. It is

capable of providing output voltages as low as

0.9V, and integrates top and bottom switches to

minimize power loss and component count. The

720KHz switching frequency allows for small

filtering components, further reducing the

solution size.

•

2A Output Current

Synchronous Rectification

Internal 160mΩ and 190mΩ Power Switches

Input Range of 2.6V to 6V

Over 90% Efficiency

Zero Current Shutdown Mode

Under Voltage Lockout Protection

Soft-Start Operation

Thermal Shutdown

Internal Current Limit (Source & Sink)

Tiny 10-Pin MSOP and 3x3 QFN Packages

The MP2108 includes cycle-by-cycle current

limiting and under voltage lockout. Internal

power switches, combined with the tiny 10-pin

MSOP or 3mm x 3mm QFN packages, provide

a solution requiring a minimum of board space.

APPLICATIONS
