Overview

MIC2285A 8MHz PWM Synchronous Buck Regulator with LDO Standby Mode General Description The Micrel MIC2285A is a high efficiency 8MHz PWM synchronous buck (step-down) regulator that features a LOWQ® LDO standby mode that draws only 20µA of quiescent current.
The MIC2285A allows an ultra-low noise, small size, and high efficiency solution for portable power applications.
In PWM mode, the MIC2285A operates with a constant frequency 8MHz 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 curr...
