NCP1200D60R2G, ШИМ-контроллер для маломощных, универсальных, автономных источников питания, [SO-8] /Код si-192573

The NCP1200D60R2G 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 60kHz, 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
