MIC2571 is a micropower boost switching regulator that operates from one alkaline, nickel-metal-hydride
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. An external SYNC connection allows the switching frequency to be synchronized to an external signal.
The MIC2571 requires only four components (diode, inductor, input capacitor and output capacitor) to implement a boost regulator. A complete regulator can be constructed in a 0.3 in² area.
All versions are available in an 8-lead MSOP with an operating range from -40°C to +85°C.
