HFC0310 Programmable Fixed-Frequency Flyback Controller DESCRIPTION The HFC0310 is a flyback controller with programmable 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.
