MIC2238  
2.5MHz Dual Phase  
PWM Buck Regulator  
General Description  
Features  
The Micrel 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.  
• Input voltage range: 2.5V to 5.5V  
• Dual output voltages running out of phase  
• 28µA quiescent current  
• Fixed output voltage versions  
• Adjustable version down to 0.8V  
• Low noise 2.5MHz PWM operation  
• 800mA output current capability for each channel  
• Stable with 2.2µH inductor, 2.2µF ceramic cap  
• Automatic switching into light load mode of operation  
• /FPWM pin allows low noise all-PWM mode operation  
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  
• Power good output with internal 5µA current source  
allows sequencing with programmable delay time  
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%.  
• Internal soft-start  
• 1μA shutdown current  
• Built-in soft-start circuitry  
• Current limit protection  
• Pb-Free 3mm x 3mm MLF®-12L package  
The MIC2238 is available in a space-saving 3mm x 3mm  
MLF®-12L package with a junction temperature range from  
-40°C to +125°C.

• Cellular phones  
• PDAs  
• Digital Cameras
