Taiwan Semiconductor’s LED driver with 4.5 V to 75 V input @ 2A


Taiwan Semiconductor‘s TS19503 is a single-channel continuous-conduction, hysteretic mode converter LED driver IC. Featuring best-in-class 4.5 V to 75 V input and 2 A output, the TS19503 offers up to 97% efficiency and 2% accuracy over a wide range of external conditions. AEC-Q100 qualification assures high reliability while the hysteretic (bang-bang) control technique provides high accuracy and reduced external parts count.


  • 4.5 V to 75 V input voltage, best-in-class; one device handles many applications
  • Wide operating temperature range: -40°C to +125°C
  • Hysteretic (bang-bang) control delivers exceptional accuracy with minimal external parts
  • Low RDS(on) internal MOSFET enables up to 97% efficiency
  • PWM and analog dimming; 1000:1 dimming range
  • Adjustable frequency to 1 MHz enables design optimization to meet EMI requirements
  • MSOP-10EP package: heatsink on package improves thermal performance
  • Internal fault status flag provides added protection against damaging faults
