MIC2124YMM More Semiconductors - ICs by Microchip Technology
Synchronous Buck Controller w/Adaptive On-Time Control
| Status: | Not Recommended |
|---|---|
| Series: | MIC2124 |
| RoHS: | Compliant |
The MIC2124 is a member of the Hyper Speed Control™ family of DC-DC controllers. It uses an adaptive on-time current mode control scheme and operates at a constant frequency.
The MIC2124 operates over a supply range of +3V to +18V, and is independent of the IC supply voltage VIN. It operates at a fixed 300kHz switching frequency and can be used to provide up to 25A of output current. The output voltage is adjustable down to +0.8V.
The MIC2124 includes an EN/COMP pin that can be pulled low to shut down the converter. The MIC2124 optimizes performance and ensures stability with external compensation.
The UVLO is provided to ensure proper operation under power-sag conditions and to make sure that the external power MOSFET has enough voltage to work with. An internal digital soft-start ensures reduced inrush current. Cycle-by-cycle current limiting ensures FET protection.
The MIC2124 is available in a 10-pin MSOP package with a junction temperature operating range from -40°C to +125°C.
