MIC2206  
2MHz PWM Synchronous Buck  
Regulator with LOWQ Mode and Voltage  
Scaling  
General Description  
Features  
The Micrel MIC2206 is a high efficiency 2MHz PWM  
synchronous buck (step-down) regulator that  
features a LOWQ™ LDO standby mode that draws  
only 18µA of quiescent current. The MIC2206  
allows an ultra-low noise, small size, and high  
efficiency solution for portable power applications.  
2.7 to 5.5V supply voltage  
Light load LOWQ™ LDO mode  
18µA quiescent current  
Low noise, 75µVrms  
2MHz PWM mode  
Output current to 600mA  
>95% efficiency  
In PWM mode, the MIC2206 operates with a  
constant frequency 2MHz PWM control. Under light  
load conditions, such as in system sleep or standby  
modes, the PWM switching operation can be  
disabled to reduce switching losses. In this light  
load LOWQ™ mode, the LDO maintains an output  
voltage of 1V and draws only 18µA of quiescent  
current. The LDO mode of operation saves battery  
life while not introducing spurious noise and high  
ripple as experienced with pulse skipping or bursting  
mode regulators.  
100% maximum duty cycle  
Output Voltage Scaling (1V output in LOWQ  
Mode)  
Ultra-fast transient response  
Stable with 1µF ceramic output capacitor  
Fully integrated MOSFET switches  
Micropower shutdown  
Thermal shutdown and current limit protection  
Pb-free 3mm x 3mm MLF-10L package  
–40°C to +125°C junction temperature range  
The MIC2206 operates from 2.7V to 5.5V input and  
features internal power MOSFETs that can supply  
up to 600mA output current in PWM mode. It can  
operate with a maximum duty cycle of 100% for use  
in low-dropout conditions.  
Applications  
The MIC2206 is available in the 3mm x 3mm MLF-  
10L package with a junction operating range from  
–40°C to +125°C.  
Cellular phones  
PDAs  
USB peripherals
