HFC0310GS - Programmable Fixed-Frequency Flyback Controller

Download the HFC0310GS datasheet PDF. This datasheet also covers the HFC0310 variant, as both devices belong to the same programmable fixed-frequency flyback controller family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key Features

  • Programmable switching frequency up to 600kHz.
  • Frequency shaping.
  • Current-mode operation.
  • Very low start-up current.
  • Very low standby power consumption via active-burst mode.
  • Internal leading-edge blanking.
  • Built-in soft-start function.
  • Internal slope compensation.
  • External protection with recovery hysteresis on PRO pin.
  • Over-temperature protection.
  • VCC under-voltage lockout with hysteresis.

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.
