ROHM BD7693FJ | Demoboard BD7693FJ-EVK-002

Flyback Type High Power Factor

Overview

TopologyBuck Converter
Input voltage90-264 V
Output 136.75 V / 1.2 A
IC revision001

Description

This evaluation board can output a voltage of 35 V isolated from an input of 90 Vac to 264 Vac, and the maximum output current is 1.2 A.The one-converter flyback type achieves a high power factor (PF > 0.9). The control IC uses BD7693FJ,which use the critical mode. Switching loss and noise are reduced by zero current detection. A circuit that lowers total harmonic distortion (THD) us used to support IEC610003-2 Class C and Class D.

Features

  • Boundary Conduction Mode PFC
  • Low THD Circuit Incorparation
  • VCC Under Voltage Lock Out Function
  • ZCD by Auxiliary Winding
  • Static OVP by The VS Pin
  • Error Amplifier Input Short Protection
  • Stable MOSFET Gate Driving
  • Soft Start Function

Typical applications

  • Lighting Equipment, AC Adopter, TV, Refrigerator, etc
