NCP3231A: High Current Synchronous Buck Converter
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
- 500KHz switching frequency
- Lossless low-side FET current sensing
- 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
| Benefits- Supports wide range of applications
- Requires small inductor and low number of output capacitors
- Good thermal performance
