MP2354

2A, 23V, 380KHz

Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2354 is a monolithic step down switch

mode converter with a built in internal power

MOSFET. It achieves 2A continuous output

current over a wide input supply range with

excellent load and line regulation.

•

0.18Ω Internal Power MOSFET Switch

Stable with Low ESR Output Ceramic

Capacitors

Up to 95% Efficiency

2A Output Current

Wide 4.75V to 23V Operating Input Range

Fixed 380KHz Frequency

Thermal Shutdown

Cycle-by-Cycle Over Current Protection

Programmable Under Voltage Lockout

Frequency Synchronization Input

Operating Temperature: –40°C to +85°C

Available in an 8-Pin SO Package

•

Current mode operation provides fast transient

response and eases loop stabilization.

Fault condition protection includes cycle-by-cycle

current limiting and thermal shutdown. In

shutdown mode the regulator draws 20µA of

supply current.
