8W at 230 VAC & 0.
5W load with Description The FSDH0170RNB/FSDH0270RNB/FSDH0370RNB consists of an integrated current mode Pulse Width Modulator (PWM) and an avalanche rugged 700V Sense FET.
It is specifically designed for high performance offline Switch Mode Power Supplies (SMPS) with minimal external components.
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 current sources for loop compensation and fault protection circuitry.
Compared to a discrete MOSFET and controller or RCC switching converter solution, the FSDH0170RNB/ FSDH0270RNB/FSDH0370RNB reduces total component count, design size, and weight while increasing efficiency, productivity, and system reliability.
These devices provide a basic platform that is well suited for the design of cost-effective flyback converters, as in PC auxiliary power supplies.
Burst-Mode Operation „ Frequency Modulation for EMI Reduction „ Precision Fixed Operating Frequency, 100kHz „ Internal Start-up Circuit and Built-in Soft Start „ Pulse-by-Pulse Current Limiting and Auto-Restart Mode „ Over Voltage Protection (OVP), Over Load Protection (OLP), Internal Thermal Shutdown Function (TSD) „ Under Voltage Lockout (UVLO) „ Low Operating Current (3mA) „ Adjustable Peak Current Limit Applications „ Auxiliary Power Supply for PC and Server „ SMPS for VCR, SVR, STB, DVD & DVCD Player „ SMPS for Printer, Facsimile & Scanner „ Adapter for Camcorder Related Application Notes „ AN-4137, AN-4141, AN-4147 (Flyback) „ AN-4134 (Forward) ...
