Both devices are integrated high voltage power switching regulators which combine an avalanche rug- ged Sense FET with a current mode PWM control block. The integrated PWM controller features include: a fixed oscillator with frequency modulation for reduced EMI, Under Voltage Lock Out (UVLO) protection, Leading Edge Blanking (LEB), an optimized gate turn-on/turn-off driver, Thermal Shut Down (TSD) protection and temperature compensated precision cur- rent sources for loop compensation and fault protection cir- cuitry. The FSDx0365RNB offers better performance in Soft Start than FSDx0365RN. When compared to a discrete MOS- FET and controller or RCC switching converter solution, the FSDx0365RNB devices reduce total component count, design size, weight while increasing efficiency, productivity, and sys- tem reliability. Both devices provide a basic platform that is well suited for the design of cost-effective flyback converters. Notes: 1. Typical continuous power in a non-ventilated enclosed adapter with sufficient drain pattern as a heat sinker, at 50 °C ambient. 2. Maximum practical continuous power in an open frame design with sufficient drain pattern as a heat sinker, at 50 °C ambient. 3. 230 VAC or 100/115 VAC with doubler. Typical Circuit Figure 1.
