Description
General part information
MIC2285A Series
The MIC2285A is a high efficiency 8MHz PWM synchronous buck (step-down) regulator that features a LowQ® LDO standby mode that draws only 18µA 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 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.
The MIC2285A 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.
