Buck Converter EVAL Board based on VIPer01
STEVAL-ISA178V1 is a compact and efficient solution for AC-DC power supplies, and performs voltage conversion from the main line down to 5 V output voltage. The power supply is set in buck topology VOUT = 5V, IOUT = 0.2A. The input voltage range is 85VAC to 265VAC and the VIPer01 switching frequency is 60KHz. The low current consumption of the VIPer01 and its low VCC voltage allows extremely low input power consumption under no load and light load conditions.
The pulse skip feature embedded in our IC reduces the peak current typically present during the startup phase of a buck converter. The VIPer01 is also equipped with a frequency reduction feature to limit excessive currents at start-up, as well as overload/short-circuit and overtemperature management.
Applications:
1) Power supplies.
