MIC2171 Datasheet 2.5a Switching Regulator

Manufacturer: Microchip Technology

Overview: MIC2171 100 kHz, 2.5A Switching Regulator.

General Description

The MIC2171 is a complete 100 kHz SMPS current-mode controller with an internal 65V 2.5A power switch.

Although primarily intended for voltage step-up applications, the floating switch architecture of the MIC2171 makes it practical for step-down, inverting, and Cuk configurations, as well as isolated topologies.

Operating from 3V to 40V, the MIC2171 draws only 7 mA of quiescent current, making it attractive for battery-operated applications.

Key Features

  • 2.5A, 65V Internal Switch Rating.
  • 3V to 40V Input Voltage Range.
  • Current Mode Operation, 2.5A Peak.
  • Internal Cycle-by-Cycle Current Limit.
  • Twice the Frequency of the LM2577.
  • Low External Electronic Components Count.
  • Suitable for Most Switching Topologies.
  • 7 mA Quiescent Current (Operating).
  • Fits LT1171/LM2577 TO-220 and TO-263 Sockets.
