HFC0310 Programmable Fixed-Frequency Flyback Controller The Future of Analog IC Technology DESCRIPTION FEATURES The HFC0310 is a flyback controller with Programmable switching frequency up to programmable fixed-frequency operation. 600kHz Frequency shaping The controller uses peak current mode to Current-mode operation provide excellent transient response and ease Very low start-up current loop compensation. When the output power falls Very low standby power consumption via below a given level, the controller enters burst active-burst mode mode to lower the stand-by power consumption. Internal leading-edge blanking An external capacitor connected between the Built-in soft-start function FSET pin and GND programs the HFC0310 Internal slope compensation switching frequency. Otherwise, the HFC0310 External protection with recovery hysteresis uses a frequency shaping function that greatly on PRO pin reduces the noise level, and reduces the cost of Over-temperature protection the EMI filter. V under-voltage lockout with hysteresis CC The HFC0310 provides various protections, Over-voltage protection on VCC such as thermal shutdown, V under-voltage CC Time-based over-load protection lockout, over-load protection, over-voltage Short-circuit protection protection, and short-circuit protection. APPLICATIONS The HFC0310 is available in a SOIC8 package. Power Meters Switching Mode Power Supplies AC/DC Adapters, Switching Chargers All MPS parts are lead-free and adhere to the RoHS directive.
