MIC2876

In Production

The MIC2876 is a compact and highly-efficient 2MHz synchronous boost regulator with a 4.8A switch. It features a bi-directional load disconnect function which prevents any leakage current between the input and output when the device is disabled. The MIC2876 operates in bypass mode automatically when the input voltage is greater than the target output voltage. At light loads, the boost converter goes to the PFM mode to improve the efficiency.

The MIC2876 also features an integrated anti-ringing switch to minimize EMI.

The MIC2876 is available in a 8-pin 2mm × 2mm Thin DFN (TDFN) package, with a junction temperature range of -40°C to +125°C.
