SN03A
High Power Factor Flyback PWM Controller
Product Specification
GENERAL DESCRIPTION
FEATURES
• Low Start-up Current and Operating Current
SN03A is a high power factor flyback PWM • Cycle-by-Cycle Current Limiting
controller special for lighting applications.
SN03A features an internal start-up timer for stand-alone applications, an analog multiplier with for power factor correction (PFC), zero current detector (ZCD) to ensure TM operation, a current sensing comparator with built-in leading-edge blanking, and a totem pole output ideally suited for driving a power MOSFET.
