    MIC2875 - 4.8A ISW, Synchronous Boost Regulator with Bi-Directional Load Discon.
    Docket ↓
    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 ...
