Micrel’s MIC2570 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.
3V and 15V.
Its typical no-load supply current is 130µA.
The MIC2570 is available in selectable fixed output or adjustable output versions.
The MIC2570-1 can be configured for 2.
85V, 3.
3V, or 5V 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 36V, using an external resistor network.
The MIC2570 has a fixed switchi...
