MIC2571
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 120 μ A.
The MIC2571 is available in selectable fixed output or adjust-
able 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 config-
ured for an output voltage ranging between its input voltage
and 36V, using an external resistor network.

Final Information
Features
? Operates from a single-cell supply
0.9V to 15V operation
? 120 μ A typical quiescent current
? Complete regulator fits 0.3 in 2 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
Applications
The MIC2571 has a fixed switching frequency of 20kHz. An
external SYNC connection allows the switching frequency to
be synchronized to an external signal.
The MIC2571 requires only four components (diode, induc-
tor, input capacitor and output capacitor) to implement a
boost regulator. A complete regulator can be constructed in
a 0.3 in 2 area.
All versions are available in an 8-lead MSOP with an operat-
ing range from –40 ° C to +85 ° .
