MIC22400  
4A Integrated Switch Synchronous  
Buck Regulator with Frequency  
Programmable up to 4MHz  
General Description  
Features  
The Micrel MIC22400 is a high-efficiency, 4A integrated  
switch synchronous buck (step-down) regulator. The  
MIC22400 is optimized for highest efficiency, achieving  
over 90% efficiency while still switching at 1MHz over a  
broad load range. The ultra-high-speed control loop keeps  
the output voltage within regulation even under extreme  
transient load swings commonly found in FPGAs and low-  
voltage ASICs. The output voltage can be adjusted down  
to 0.7V to address all low-voltage power needs. The  
MIC22400 gives a full range of sequencing and tracking  
options. The EN/DLY pin combined with the Power-On-  
Reset (POR) pin allows multiple outputs to be sequenced  
in any way on turn-on and turn-off. The Ramp Control™  
(RC) pin allows the device to be connected to another  
MIC22400 family of products to keep the output voltages  
within a certain ΔV on start-up.  
• Input voltage range: 2.6V to 5.5V  
• Output voltage adjustable down to 0.7V  
• Output load current up to 4A  
• Full sequencing and tracking ability  
• Power-On-Reset (POR)  
• Efficiency > 90% across a broad load range  
• Programmable frequency 300kHz to 4MHz  
• Easy Ramp Control™ (RC) compensation  
• Ultra-fast transient response  
• 100% maximum duty cycle  
• Fully-integrated MOSFET switches  
• Micropower shutdown  
• Thermal-shutdown and current-limit protection  
• 20-pin 3mm x 4mm MLF®  
The MIC22400 is available in a 20-pin 3mm x 4mm MLF®  
and thermally-enhanced 20-pin ePad TSSOP with a  
junction operating range from –40°C to +125°C.  
• 20-pin ePad TSSOP  
• –40°C to +125°C junction temperature range  
Data sheets and support documentation can be found on  
Micrel’s web site at: www.micrel.com.  
Applications  
• High power density point-of-load conversion  
• Servers and routers  
• DVD recorders  
• Computing peripherals  
• Base stations  
• FPGAs, DSP and low-voltage ASIC power
