The MIC2238 is dual output 2-phase synchronous buck (step down) PWM DC/DC switching regulator. Power conversion efficiencies of above 95% are easily obtainable for a wide range of applications and loads. An ultra-low quiescent current of 28µA at light loads assures minimum current draw in battery powered applications that require standby modes. The 2.5MHz PWM operation of MIC2238 allows the use of miniature 1µH, 2.2µH or 4.7µH inductor with the use of 2.2µF ceramic output capacitor.

The MIC2238 operates from 2.5V to 5.5V input and is available in fixed output voltage versions to save space and reduce external component count. The MIC2238-AA's (adjustable version) output voltage versions can be programmed as low as 0.8V

For applications that require the lowest noise performance, the /FPWM pin allows the automatic Trickle mode to be disabled, remaining in full PWM mode. To maximize battery life in low-dropout conditions, MIC2238 can operate with a maximum duty cycle of 100%.
