FSL116HR Green-Mode Power Switch Description The FSL116HR integrated Pulse Width Modulator (PWM) and SENSEFET is specifically designed for high performance offline SwitchedMode Power Supplies (SMPS) with minimal external www.onsemi.com components. FSL116HR includes integrated highvoltage power switching regulators that combine an avalancherugged SENSEFET with a CurrentMode PWM control block. The integrated PWM controller includes: UnderVoltage Lockout (UVLO) protection, LeadingEdge Blanking (LEB), a frequency generator for EMI attenuation, an optimized gate turnon / turnoff driver, Thermal Shutdown (TSD) protection, and temperature compensated precision current sources for loop compensation and PDIP8 9.42x6.38, 2.54P CASE 646CM faultprotection circuitry. The FSL116HR offers good softstart performance. When compared to a discrete MOSFET and controller or RCC switching converter solution, the FSL116HR reduces total MARKING DIAGRAM component count, design size, and weight while increasing efficiency, Y&E&Z&2&K productivity, and system reliability. This device provides a basic FSL116HR platform that is well suited for the design of costeffective flyback converters.
