Package Drawing:
The NCP1247 is a new fixed-frequency current-mode PWM controller featuring Dynamic Self-Supply. This function greatly simplifies the design of the auxiliary supply and the Vcc capacitor by activating the internal startup current source to supply the controller during start-up, transients, latch, stand-by etc. This device contains a special HV detector which detects the application unplug from the AC input line and triggers the X2 discharge current. The HV structure also includes brown-out detection circuitry. The NCP1247 features a timer-based fault detection that ensures the detection of overload and an adjustable power compensation to help keep the maximum power independent of the input voltage. Due to frequency foldback, the controller exhibits excellent efficiency in light load condition while still achieving very low standby power consumption. Internal frequency jittering, ramp compensation, and a versatile latch input make this controller an excellent candidate for robust power supply designs. A dedicated off mode allows the SMPS to reach extremely low no load input power consumption when combined with secondary side controller NCP4353 or NCP4354. When used together, the SMPS is capable of achieving <10 mW no load input power consumption. The secondary side controller signals the NCP1247 to enter a sleep mode, minimizing the power consumption of the control circuitry. The NCP1247 is very similar in its functionality to the NCP1246. The NCP1247 is designed to get better performance out of systems with synchronous rectification. NCP1247 - Adds C & D option for different Brown Out threshold- Enhanced operation with Sync Rec in light load- Increased HV timer- Revised X2 discharge sequenceThis product is IEC60950 compliant. Please see the test report and certification in the Conformance report section below.
