Step-Down Buck DC-DC Converter
Advanced Power Electronics  (San Jose, CA) has introduced the APE1723-HF-3, a 200kHz 1A PWM buck DC-DC convertor with an adjustable output voltage range from 0.745 to 24 V. The APE1723-HF-3 can drive a 1A load without an external transistor, saving considerable board real estate. Features include:
- Operates at a fixed switching frequency of 200 kHz, enabling simpler filter components to be used in a design.
- Thermal shutdown for protection against damage in the event of over-temperature operation.
- Current limit protection and short circuit protection to safeguard the output switch.
- Output voltage tolerance is guaranteed at ±3% under specified input voltage and output load conditions.
