2A, 23V, 370KHz

Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2358 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.

•

2A Output Current with QFN Package

0.18Ω Internal Power MOSFET Switch

Stable with Low ESR Output Ceramic

Capacitors

93% Efficiency

23µA Shutdown Mode

•

Current mode operation provides fast transient

response and eases loop stabilization.

Fixed 370KHz Frequency

Thermal Shutdown

Fault condition protection includes cycle-by-cycle

current limiting and thermal shutdown. In

shutdown mode the regulator draws 23µA of

Cycle-by-Cycle Over Current Protection

Wide 4.75V to 23V Operating Input Range

Output Adjustable from 0.92V to 16V

Programmable Under Voltage Lockout

Available in QFN10 (3mm x 3mm) and SO8

Packages

current.

Programmable

soft-start

minimizes the inrush supply current and the

output overshoot at initial startup.

The MP2358 requires a minimum number of

readily available standard external components.
