NCP1027P065G
High-Voltage Switcher for Medium Power Offline SMPS Featuring Low Standby Power
交流/直流转换器 PWM Current Mode Controller
The NCP1027P065G NCP1027 offers a new solution targeting output power levels from a few watts up to 15 W in a universal mains flyback application. Our proprietary high−voltage technology lets us include a power MOSFET together with a startup current source, all directly connected to the bulk capacitor. To prevent lethal runaway in low input voltage conditions, an adjustable brown−out circuitry blocks the activity until sufficient input level is reached.
NCP1027P065G Features
• Built−in 700 V MOSFET with Typical RDS(on) of 5.8 , TJ = 25°C
• Current−Mode Fixed Frequency Operation: 65 kHz and 100 kHz
• Fixed Peak Current of 800 mA
• Skip−Cycle Operation at Low Peak Currents
• Internal Current Source for Clean and Lossless Startup Sequence
• Auto−Recovery Output Short Circuit Protection with Timer−Based Detection
• Auto−Recovery Overvoltage Protection with Auxiliary Winding Operation
• Programmable Brown−Out Input for Low Input Voltage Detection
• Programmable Over Power Protection
• Input to Permanently Latchoff the Part
• Internal Frequency Jittering for Improved EMI Signature
• Extended Duty Cycle Operation to 80% Typical
• No−Load Input Standby Power of 85 mW @ 265 Vac
