MIC2141
Micropower Boost Converter
General Description
Features
The MIC2141 is a micropower boost switching
regulator that can operate from 3- or 4-cell nickel-metal-hydride batteries or a single Li-ion cell.
This
regulator employs a constant 330kHz, fixed 18% duty-cycle, gated-oscillator architecture.
The MIC2141 can be used in applications where the output voltage must be dynamically adjusted.
The device features a control signal input which is used to proportionally adjust the output voltage.
The control signal input has a gain of 6, allowing a 0.
8V to 3.
6V control signal to vary a 4.
8V to 22V output.
The MIC2141 requires only three external components to operate and is available in a ...
