Features & Applications

The MIC2570-2YM is a micropower boost switching regulator that operates from two alkaline, two nickel-metal-hydride cells, or one lithium cell.The MIC2570 accepts a positive input voltage between 1.3 V and 15 V. Its typical no-load supply current is 130 µA.

The MIC2570 is available in selectable fixed output or adjustable output versions. The MIC2570-1 can be configured for 2.85 V, 3.3 V, or 5 V by connecting one of three separate feedback pins to the output. The MIC2570-2 can be configured for an output voltage ranging between its input voltage and 36 V, using an external resistor network.

Features:

  • Operates from a two-cell supply
  • 1.3 V to 15 V operation
  • 130µA typical quiescent current
  • Complete regulator fits 0.6 in2 area
  • 2.85 V/3.3 V/5 V selectable output voltage (MIC2570-1)
  • Adjustable output up to 36 V (MIC2570-2)
  • 1 A current limited pass element
  • Frequency synchronization input
  • 8-lead SOIC package
