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).

Features

• Large Creepage Distance Between High-Voltage Pins
• Below 100 mW Standby Power if Auxiliary Winding is Used
• Internal Temperature Shutdown
• Direct Optocoupler Connection
• SPICE Models Available for TRANsient Analysis
• Current-Mode Fixed Frequency Operation: 65 kHz - 100 kHz - 130 kHz
