NCP1580 Datasheet | onsemi

Low Voltage Synchronous Buck Controller The NCP1580 is a voltage mode PWM controller designed to operate from a 5.0 V or 12 V supply and produce an output voltage as low as 0.8 V. This 8- pin device provides an optimal level of integration to reduce size and cost of the power supply. The NCP1580 has a fixed 350 k Hz oscillator and soft- start function. The NCP1580 provides a 1.5 A floating gate driver design to drive N- Channel MOSFETs in a synchronous configuration. Adaptive non- overlap circuitry reduces switching losses by preventing simultaneous conduction of both outputs. Protection Features include thermal shutdown and undervoltage lockout (UVLO). The NCP1580 is available in an 8- pin SOIC package.
