Overview

A1 A1semi Electronics Ltd AS54303A 400KHz Synchronous Rectified Step-Down Converter GENERAL DESCRIPTION The AS5430 is a monolithic synchronous buck regulator.
The device integrates 100mΩ MOSFETS that provide 3A continuous load current over a wide operating input voltage of 4.
75V to 23V.
Current mode control provides fast transient response and cycle-by-cycle current limit.
An adjustable soft-start prevents inrush current at turn-on.
In shutdown mode, the supply current drops below 1uA.
The device provides a very compact system solution with minimal reliance on external components.
FEATURES 3A Output Current Integrated 100mΩ Power MOSFETS Wide 4.
75~23V Input Voltage Range Programmable Soft-start Up to 95% Efficiency Stable with Low ESR Ceramic Output Capacitors Output Adjustable From 0.
925V to 20V Cycle-by-Cycle Over Current Protection Input Under Voltage Lockout Fixed 400KHz Frequency APPLICATION Distribute Power Supply Networking Systems Notebook or...
