Description

General part information

MIC22950 Series

The MIC22950 is a high efficiency 10A integrated switch synchronous buck (step-down) regulator. The MIC22950 switching frequency is programmable from 400kHz to 2MHz, allowing the customer to optimize designing either for efficiency or for the smallest footprint. The MIC22950 achieves over 95% efficiency while still switching at 2MHz over a broad load range.

The ultra-high speed control loop keeps the output voltage within regulation, even under extreme transient load swings commonly found in FPGAs and low voltage ASICs. The output voltage can be adjusted down to 0.7V in order to address all low voltage power needs.

The MIC22950 features a full range of sequencing and tracking options. The enable and the delay pins, combined with the power good pin, allow multiple outputs to be sequenced in several ways during turn on and turn off. The RC (Ramp Control™) pin allows the device to be connected to any another device in the MIC22x00 family of products, to keep the output voltages within a certain delta V during start up.
