Microchip MIC2132YML | Demoboard MIC2132 4 Phase Evaluation Board

Beschreibung

The MIC2132 is a constant on-time, dual phase synchronous buck controller featuring a unique adaptive on-time control architecture with a stackable feature of up to eight phases. The MIC2132 operates over an input supply range from 4.5V to 75V and can be used to supply up to 50A of output current/phase. The output voltage is adjustable down to 0.6V with an ensured accuracy of ±1%. The device operates with a programmable switching frequency from 100 kHz to 800 kHz per phase.The MIC2132 is available in a 32-pin 5 mm x 5 mm VQFN package, with a -40°C to +125°C junction operating temperature range.
