NCP1012 Product details

The NCP101X series integrates a fixed−frequency current−mode controller and a 700 V MOSFET. Housed in a PDIP−7, PDIP−7 Gull Wing, or SOT−223 package, the NCP101X offers everything needed to build a rugged and low−cost power supply, including soft−start, frequency jittering, short−circuit protection, skip−cycle, a maximum peak current setpoint and a Dynamic Self−Supply (no need for an auxiliary winding).
Unlike other monolithic solutions, the NCP101X is quiet by nature: during nominal load operation, the part switches at one of the available frequencies (65 − 100 − 130 kHz). 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. Because this occurs at typically 1/4 of the maximum peak value, no acoustic noise takes place. As a result, standby power is reduced to the minimum without acoustic noise generation.

Features
• Built−in 700 V MOSFET with Typical RDSon of 11Ω and 22Ω
• Large Creepage Distance Between High−Voltage Pins
• Current−Mode Fixed Frequency Operation: 65 kHz – 100 kHz − 130 kHz
• Skip−Cycle Operation at Low Peak Currents Only: No Acoustic Noise!
• Dynamic Self−Supply, No Need for an Auxiliary Winding
• Internal 1.0 ms Soft−Start
• Latched Overvoltage Protection with Auxiliary Winding Operation
• Frequency Jittering for Better EMI Signature
• Auto−Recovery Internal Output Short−Circuit Protection
• Below 100 mW Standby Power if Auxiliary Winding is Used
• Internal Temperature Shutdown
• Direct Optocoupler Connection
• SPICE Models Available for TRANsient Analysis
• Pb−Free Packages are Available*

Typical Applications
• Low Power AC/DC Adapters for Chargers
• Auxiliary Power Supplies (USB, Appliances, TVs, etc.)
