MIC2875
4.8A ISW, Synchronous Boost Regulator
with Bi-Directional Load Disconnect
Features General Description Up to 95% Efficiency Input Voltage Range: 2.5V to 5.5V Fully-Integrated, High-Efficiency, 2 MHz
Synchronous Boost Regulator Bi-Directional True Load Disconnect Integrated Anti-Ringing Switch Minimum Switching Frequency of 45 kHz <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 TDFN Package The MIC2875 is a compact and highly-efficient 2 MHz
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 MIC2875
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 The MIC2875 is available in a 8-pin 2 mm Г— 2 mm Thin
DFN (TDFN) package, with a junction temperature
range of –40°C to +125°C. Tablet and Smartphones
USB OTG and HDMI Hosts
Portable Power Reserve Supplies
Low-Noise Audio Applications
Portable Equipment To minimize switching artifacts in the audio band, the
MIC2875 is designed to operate with a minimum
switching frequency of 45 kHz. The MIC2875 also
features an integrated anti-ringing switch to minimize
EMI. Package Type …
