Description
General part information
MIC94325 Series
The MIC943x5 Ripple Blocker™ is a monolithic integrated circuit that provides low-frequency ripple attenuation (switching noise rejection) to a regulated output voltage. This is important for applications where a DC/DC switching converter is required to lower or raise a battery voltage but where switching noise cannot be tolerated by sensitive downstream circuits such as in RF applications. The MIC943x5 maintains high power supply ripple rejection (PSRR) with input voltages operating near the output voltage level to improve overall system efficiency. A low-voltage logic enable pin facilitates ON/OFF control at typical GPIO voltage levels.
The MIC943x5 operates from an input voltage of 1.8V to 3.6V. The MIC943x5 options include fixed (MIC94345/55) or adjustable (MIC94325) output voltages. The MIC94355 version offers an auto-discharge to discharge the output capacitor when the part is disabled.
Packaged in a 6-pin 1.6mm x 1.6mm Thin DFN, the MIC943x5 has a junction operating temperature range of -40°C to +125°C.
