Product Overview

The NCP1203GEVB is an evaluation board designed around a PDIP8 package of NCP1203 fixed frequency flyback current mode PWM controller. The NCP1203 represents a major leap toward ultra compact switch mode power supplies. Due to a novel concept, the circuit allows the implementation of a complete offline battery charger or a standby SMPS with few external components. Furthermore, an integrated output short circuit protection lets the designer build an extremely low cost AC to DC wall adapter associated with a simplified feedback scheme. The power supply features short circuit and overvoltage protection, and delivers a 70W output at an efficiency greater than 80%.
  • High voltage start up current source
  • Auto recovery internal output short circuit protection
  • Extremely low no load standby power
  • Current mode with adjustable skip cycle capability
  • Internal leading edge blanking
  • 250mA peak current capability
  • Direct optocoupler connection
  • Undervoltage lockout at 7.6V typical
  • Internally fixed frequency at 40KHz, 60KHz and 100KHz
