MIC2876
4.8A ISW, Synchronous Boost Regulator
with Bi-Directional Load Disconnect
Features General Description Up to 95% Efficiency Input Voltage Range from 2.5V to 5.5V Fully Integrated, High-Efficiency, 2 MHz
Synchronous Boost Regulator Bi-Directional True Load Disconnect Integrated Anti-Ringing Switch <1 µA Shutdown Current Bypass Mode for VIN ≥ VOUT Overcurrent Protection and Thermal Shutdown Fixed and Adjustable Output Versions 8-pin 2 mm × 2 mm UDFN package 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. Applications Tablets and Smartphones
USB OTG and HDMI Hosts
Portable Power Reserve Supplies
High-Current Parallel Lithium Cell Applications
Portable Equipment The MIC2876 also features an integrated anti-ringing
switch to minimize EMI.
The MIC2876 is available in a 8-pin 2 mm Г— 2 mm
UDFN package, with a junction temperature range of
–40°C to +125°C. Package Types
