MIC2571 - Single-Cell Switching Regulator Preliminary Information

General Description

Micrel’s MIC2571 is a micropower boost switching regulator that operates from one alkaline, nickel-metal-hydride cell, or lithium cell.

The MIC2571 accepts a positive input voltage between 0.9V and 15V.

Its typical no-load supply current is 120µA.

Key Features

  • Operates from a single-cell supply 0.9V to 15V operation.
  • 120µA typical quiescent current.
  • Complete regulator fits 0.3 in2 area.
  • 2.85V/3.3V/5V selectable output voltage (MIC2571-1).
  • Adjustable output up to 36V (MIC2571-2).
  • 1A current limited pass element.
  • Frequency synchronization input.
  • 8-lead MSOP package.

MIC2571 Micrel MIC2571 Single-Cell Switching Regulator Preliminary Information General Description Micrel’s MIC2571 is a micropower boost switching regulator that operates from one alkaline, nickel-metal-hydride cell, or lithium cell. The MIC2571 accepts a positive input voltage between 0.9V and 15V. Its typical no-load supply current is 120µA. The MIC2571 is available in selectable fixed output or adjustable output versions. The MIC2571-1 can be configured for 2.85V, 3.3V, or 5V by connecting one of three separate feedback pins to the output. The MIC2571-2 can be configured for an output voltage ranging between its input voltage and 36V, using an external resistor network. The MIC2571 has a fixed switching frequency of 20kHz.
