The EVHFC0310A-S-00A is an evaluation board designed to demonstrate the capabilities of the HFC0310A. The HFC0310A is a flyback controller that is configured to provide a 3-channel output, including a main-controlled 12.5V/3A output from a 100V_DC to 1000V_DC input.

The HFC0310A uses peak current mode to provide excellent transient response and ease loop compensation. When the output power (P_OUT) falls below a given level, the controller enters burst mode to reduce standby power consumption.

An external capacitor connected between the FSET and GND pins configures the HFC0310A’s switching frequency (f_SW). Otherwise, the HFC0310A uses a frequency shaping function to reduce the noise level and cost of the EMI filter.

The HFC0310A is available in an SOIC-8 package.
