The Micrel MIC2206 is a high efficiency 2MHz PWM synchronous buck (step-down) regulator that features a LOWQ?LDO standby mode that draws only 18mA of quiescent current. The MIC2206 allows an ultra-low noise, small size, and high efficiency solution for portable power applications.
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 18mp of quiescent current. The LDO MIC2206 mode of operation saves battery life while not introducing spurious noise and high ripple as experienced with pulse skipping or bursting mode regulators.
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.
The MIC2206 is available in the 3mm x 3mm MLF-10L package with a junction operating range from ?0 to +125.
