ONSEMI NCP1200D100R2G PWM Controller for Low-Power Supplies
The NCP1200 is a current-mode PWM controller designed for low-power off-line power supplies and battery chargers. It features fixed internal oscillation frequencies of 40 kHz, 60 kHz, or 100 kHz, operates without an auxiliary winding by using a dynamic self-supply system, and includes built-in protections like output short-circuit and overload detection. Its high efficiency at light loads with skip-cycle mode, low standby power, and direct optocoupler connection make it ideal for disposable and compact AC-DC adapters, auxiliary power supplies, and consumer electronics. The device simplifies design while ensuring reliable, low-noise operation.
