HT7A6312 - Low Power Primary Switcher

Description

The HT7A6312 is highly functionally integrated device which combines an integrated PWM controller with current mode control and a high voltage power MOSFET on the same silicon chip.

Features

  • Fixed 60kHz switching frequency.
  • 9V to 38V wide range VCC voltage.
  • Wide AC input range from 85VAC to 265VAC.
  • PWM with current mode control.
  • Auxiliary Under Voltage Lock Out with hysteresis.
  • High voltage start-up current source.
  • Excellent standby low power consumption.
  • Over-temperature, Over-current and Over-voltage protection with auto-restart.
  • Integrated 730V MOSFET.
  • Burst mode under low load co.
