LYT7503D General Description

LYTSwitch™-7 family phase-cut dimmable single-stage LED driver IC with combined PFC and constant current output for buck topology is ideal for single-stage, high PF, constant current LED dimmable applications. The 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 CrM operation results in low turn-on losses and reduces cost of output diode (slower reverse-recovery type can be used). LYTSwitch-7 devices are suitable for applications from 4W to 22W. LYTSwitch-7 peak current mode operation is suitable for TRIAC applications without the need for an active bleeder. Over-temperature shutdown provides protection during fault conditions. Thermal foldback ensures that light continues to be delivered at elevated temperatures.

Key Features

  • Comprehensive protection features with auto-restart
  • Single-stage PFC + accurate CC output, design flexibility, highest reliability
  • ±3% CC regulation in single line input voltage applications, power factor>0.9, high efficiency>85%
  • Robust 725V MOSFET for increased line voltage surge resistance, critical conduction mode (CrM) buck
  • Low EMI, excellent line noise and transient rejection Fast turn-on (<500ms), low pop-on
  • Better than 10:1 dimming ratio, simple passive R-C damper, monotonic dimming profile
  • Wide input (90VAC - 308VAC) and output voltage range operation, requires no inductor bias winding
  • 2 family members cover power range for optimum device selection
  • Industry's lowest component count dimming solution
  • Advanced thermal control, input/output overvoltage protection, output short-circuit protection
