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.  
Implements low-power boost, SEPIC, or flyback  
2.2V to 14V input voltage  
330kHz switching frequency  
<2µA shutdown current  
70µA quiescent current  
1.24V bandgap reference  
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  
Typical output current 1mA to 10mA  
SOT23-5 package  
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.  
Applications  
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%.  
LCD bias supply  
CCD digital camera supply
