MIC2205 www.DataSheet4U.com 2MHz PWM Synchronous Buck Regulator with LDO Standby Mode General Description The Micrel MIC2205 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 MIC2205 allows an ultra-low noise, small size, and high efficiency solution for portable power applications. In PWM mode, the MIC2205 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 the output voltage and draws only 18µA of quiescent current.
