LSP5503 - 3A Synchronous Step Down DC/DC Converter

Datasheet Summary

Description

The LSP5503 is a monolithic synchronous buck regulator.

The device integrates 100mΩ MOSFETS that provide 3A continuous load cur-rent over a wide operating input voltage of 4.5V to 27V.

Current mode control provides fast transient response and cycle-by-cycle cur-rent limit.

Features

3A Output Current Wide 4.5V to 27V Operating Input Range Integrated 100mΩ Power MOSFET Switches Output Adjustable from 0.925V to 24V Up to 96% Efficiency Programmable Soft-Start Stable with Low ESR Ceramic Output Capacitors Fixed 400KHz Frequency Cycle-by-Cycle Over Current Protection Input Under Voltage Lockout SOP8L-EP Package.
