Product Overview

The NCP1200P100G is a current-mode Pulse Width Modulation (PWM) Controller for low-power universal off-line supplies. It represents a major leap toward ultra-compact switchmode 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. With an internal structure operating at a fixed 100kHz, the controller drives low gate-charge switching devices like an IGBT or a MOSFET thus requiring a very small operating power. Due to current-mode control, the NCP1200 drastically simplifies the design of reliable and cheap offline converters with extremely low acoustic generation and inherent pulse-by-pulse control.
  • No auxiliary winding operation
  • Internal output short-circuit protection
  • Extremely low no-load standby power
  • Current-mode with skip-cycle capability
  • Internal leading edge blanking
  • 250mA Peak current source/sink capability
  • Direct optocoupler connection
  • Built-in frequency jittering for lower EMI
  • Internal temperature shutdown
