Micrel MIC2141
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.| Part No. | MIC2141 |

GENERAL DESCRIPTION
FEATURES
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 tiny 5-pin SOT-23 package for space and power-sensitive portable applications. The MIC2141 draws only 70µA of quiescent current and can operate with an efficiency exceeding 85%. Data sheets and support documentation can be found on Micrel’s web site at:● Implements low-power b
