MIC2230
Dual Synchronous 800mA/800mA
Step-Down DC/DC Regulator
General Description
Features
The MIC2230 is dual output, high-efficiency synchronous
step-down DC/DC converter. The MIC2230 is ideally
suited for portable systems which 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

High Efficiency: Over 96%
Ultra-low quiescent current: Only 28μA
Ultra-low shutdown current less than 1μA
Fast transient performance
2.5MHz PWM operation
minimum current draw from battery powered applications
in standby modes. The MIC2230 was designed to only
require miniature 2.2μH inductors and 10μF ceramic
capacitors.
The MIC2230 features a selectable mode that allows the
user to trade-off lowest noise performance for low power
efficiency. Trickle Mode TM operation provides ultra-high
efficiency at light loads, while PWM operation provides
very low ripple noise performance. To maximize battery life
in low-dropout conditions, MIC2230 can operate with a
maximum duty cycle of 100%.
The MIC2230 is available in a space-saving 3mm × 3mm
MLF ? -12L package with a junction temperature range from
–40 ° C to +125 ° C.
