Product Overview

LYTSwitch™-1 family is ideal for single-stage, high PF, constant current LED bulbs and tubes. This single-stage LED driver IC with combined PFC and constant current output for buck topology family incorporates a high-voltage MOSFET with a variable on-time CrM controller. Extensive protection features with minimum external components provide industry leading power density and functionality. The devices can be used in high-side or low-side non-isolated buck topology. The CrM operation results in low turn-on losses and reduces cost of output diode (slower reverse recovery). LYTSwitch-1 devices are suitable for applications from 2W to 22W.
  • Output power of 7.5W at VOUT ≤ 30V, 15W at VOUT ≥ 55V (optimized for lowest THD)
  • ±3% CC regulation in single line input voltage applications, power factor of 0.9
  • High efficiency of 93%, robust 725 V MOSFET for increased line voltage surge performance
  • Critical conduction mode (CrM) buck, low EMI, excellent line noise and transient rejection
  • Design flexibility and highest reliability
  • Supports high- and low-side buck topologies Lowest component count
  • Wide input (90VAC – 308VAC) and output voltage range operation
  • 3 family members cover power range for optimum device selection
  • Comprehensive protection features with auto-restart
  • Advanced thermal control, overtemperature shutdown provides protection during fault conditions
