NCP1580 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 kHz 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. Features • Input Voltage Range from 4.5 V to 13.
