Produktbeschreibung

The NCP1216D65R2G is a current-mode Pulse Width Modulation (PWM) Controller for high-power universal off-line supplies. Due to its high drive capability, It drives large gate-charge MOSFETs, which together with internal ramp compensation and built-in frequency jittering, ease the design of modern AC to DC adapters. With an internal structure operating at different fixed frequencies, the controller supplies itself from the high-voltage rail, avoiding the need of an auxiliary winding. The current-mode control also provides an excellent input audio susceptibility and inherent pulse-by-pulse control. Internal ramp compensation easily prevents sub-harmonic oscillations from taking place in continuous conduction mode designs. When the current setpoint falls below a given value, e.g. the output power demand diminishes, the IC automatically enters the so-called skip cycle mode and provides excellent efficiency at light loads.
  • No auxiliary winding operation
  • Current-mode control with adjustable skip-cycle capability
  • Internal ramp compensation
  • Built-in frequency jittering for better EMI signature
  • Auto-recovery internal output short-circuit protection
  • Extremely low no-load standby power
  • 500mA Peak current capability
  • Internal temperature shutdown
  • Direct optocoupler connection
