    High-Speed, Low-Side PWM Controller
    Features: Description: High-Speed PWM Controller with Integrated
    Low-Side MOSFET Driver Multiple Switching Frequency Options (fSW):
    -300 kHz
    -600 kHz Adjustable Reference Voltage Generator Adjustable Soft Start Internal Slope Compensation Shutdown Input Pin (EN) Low Operating Current: < 5 mA (typical) Undervoltage Lockout (UVLO) Protection Output Short Circuit Protection Overtemperature Protection Operating Temperature Range:
    -40В°C to +125В°C The MCP1632 high-speed PWM controller is a
    pulse-width modulator developed for stand-alone power
    supply applications. The MCP1632 includes a
    high-speed analog control loop, a logic-level MOSFET
    driver, an internal oscillator, a reference voltage
    generator, and internal slope compensation. This high
    level of integration makes it an ideal solution for
    standalone SMPS applications. MCP1632 is suitable for
    use in topologies requiring a low-side MOSFET control,
    such as Boost, Flyback, SEPIC, Д†uk, etc. Typical
    applications include battery chargers, intelligent power
    systems, brick DC-DC converters, LED drivers. Due to
    its low power consumption, the MCP1632 PWM
    controller is recommended for battery-operated
    applications. Applications: Switch Mode Power Supplies
    Brick DC-DC Converters
    Battery Charger Applications ...
