DESCRIPTION
The EVHFC0310-S-00A is an evaluation board
for the HFC0310. It is configured to provide a
regulated 12V output at up to 0.6A load current,
and 6V output at up to 0.1A load current from a
85V
AC
- 420V
AC
input.
HFC0310 uses peak current mode to provide
excellent transient response and ease loop
compensation. When the output power falls
below a given level, the controller enters burst
mode to lower the stand-by power consumption.
An external capacitor connected between the
FSET pin and GND programs the HFC0310
switching frequency. Otherwise, the HFC0310
uses a frequency shaping function that greatly
reduces the noise level, and reduces the cost of
the EMI filter.
