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.
