General Description
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.

Features
• Implements low-power boost, SEPIC, or flyback
• 2.5V to 14V input voltage
• 330kHz switching frequency
• <2µA shutdown current
• 70µA quiescent current
• 1.24V bandgap reference
• typical output current 1mA to 10mA
• SOT-23-5 Package

Applications
• LCD bias supply
• CCD digital camera supply
