MIC2230
Dual Synchronous 800 mA/800 mA Step-Down DC/DC Regulator
Features General Description The MIC2230 is a dual output, high-efficiency
synchronous step-down DC/DC converter. The
MIC2230 is ideally suited for portable and embedded
systems that demand high power conversion
efficiencies and fast transient performance, while
offered in a very small package. The MIC2230 offers an
ultra-low quiescent current in light load mode, assuring
minimum current draw from battery powered
applications in standby modes. The MIC2230 was
designed to only require miniature 2.2 ОјH inductors
and 10 ОјF ceramic capacitors. High Efficiency: Over 96%
Ultra-Low Quiescent Current: Only 28 ОјA
Ultra-Low Shutdown Current: Less Than 1 ОјA
Fast Transient Performance
2.5 MHz PWM Operation
High Output Current Capability per Channel:
800 mA
No Schottky Diodes Required
Stable with 2.2 ОјH Inductor, 10 ОјF Ceramic
Capacitor
Adjustable Output Voltage Down to 0.8V …
