Product 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 85VAC - 420VAC 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.

Product Features

  • Programmable switching frequency up to 600kHz

IC Details

The HFC0310 is a flyback controller with fixed-frequency operation.?The controller 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. The HFC0310 provides various protections, such as thermal shutdown, VCC under-voltage lockout, over-load protection, over-voltage protection, and short-circuit protection. The HFC0310 is available in a SOIC8 package.
