General Description

The MIC2876 is a compact and highly efficient 2 MHz

synchronous boost regulator with a 4.8A switch. It

features a bi-directional load disconnect function that

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 2 mm × 2 mm

UDFN package, with a junction temperature range of

–40°C to +125°C.
