  • The NCP3231A is a high current, high efficiency voltage-mode synchronous buck converter which operates from 4.5 V to 18 V input and generates output voltages down to 0.6 V at up to 25 A.
  • Features
  • Wide input voltage range from 4.5V to 18V - Supports wide range of applications
  • 500KHz switching frequency - Requires small inductor and low number of output capacitors
  • Lossless low-side FET current sensing - Good thermal performance
  • 0.6V internal reference voltage
  • External programmable soft-start
  • Output over-voltage and under-voltage protection
  • System over-temperature protection using a thermistor or sensor through OTS pin
  • Hiccup mode operation for all faults
  • Pre-bias start-up
  • Adjustable output voltage
  • Power good indicator
  • Internal over-temperature protection
