Device Overview

Summary

The MIC25400 is a synchronous PWM dual output step down converter with internal 2A high-side switches. The MIC25400 has an integrated low-side gate driver for synchronous step-down conversion by connecting an external N-channel MOSFET to achieve high efficiencies in low duty-cycle applications. The ICs switching frequency is 1MHz. A patented control scheme allows the use of a wide range of output capacitance from small ceramic capacitors to large electrolytic types with only one compensation component. A 2% output voltage tolerance over the temperature range allows the maximum level of system performance. The MIC25400 power good signal allows full control for sequencing the output voltages with minimum external components.

An adjustable current limit allows the use of smaller inductors in lower current applications. The MIC25400 is available in the ePAD 24-pin 4mm x 4mm MLF® package, and has an operating junction temperature range of -40°C to +125°C.
