Product Overview

1.5W double output buck demonstration board based on the VIPER16LD, a new off-line high voltage converter which has been specifically developed for non-isolated SMPS. Output regulation is easily achieved through a voltage divider to the output voltage. The VIPER16LD can work with or without an external supply. In the former case, very low standby consumption is possible ( 50mW at 265VAC) while in the latter case, the cost and complication of the IC supply network may be reduced. The other features of the device include an 800V avalanche rugged power section, PWM operation at 60KHz with frequency jittering for lower EMI, limiting current with adjustable set point, on-board soft-start and safe auto-restart after a fault condition. The available protection features are thermal shutdown with hysteresis and delayed overload protection.
  • Input voltage range (VIN) from 90VRMS to 265VRMS
  • Output voltage 1 (VOUT1) is 12V
  • Max output current 1: (IOUT1) is 0.1A
  • Output voltage 2: (VOUT2) is 5V (through LDO)
  • Max output current 2: (IOUT2) is 0.05A
  • Precision of output regulation ΔVOUT
  • LF is ±5%
  • High frequency output voltage ripple ΔVOUT
  • HF is 50mV
  • Maximum ambient operating temperature TA is 60°C
