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 8pin 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 softstart function. The NCP1580
provides a 1.5 A floating gate driver design to drive NChannel
MOSFETs in a synchronous configuration. Adaptive nonoverlap
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 8pin SOIC package.
