  • Product introduction

The A6262 is linear and programmableCurrent regulator, which provides 100 mA each of the four outputs to drive the high-brightness LED array. The regulated LED current for each output (accurate to 5%) is set by a single reference resistor. Without the use of ballast resistors, the current matching per string is better than 10%. The use of constant current drives LEDs to ensure safe operation and provide the maximum possible illumination output.

Provides output control by enabling input instructions to provide direct control for PWM applications; On/off toggle operation via debounce switch input.

For automotive applications, optimal performance is achieved when using 1 to 3 LEDs in each string to drive 4 strings with a total current of up to 100 mA each. The outputs can be paralleled or idle as needed.

Provides short-circuit detection to protect the LED and A6262 when any LED output pin is shorted to ground. When the short circuit is eliminated, the output will automatically resume the regulated current.

Temperature monitors are included to reduce LED drive current if the die temperature exceeds an adjustable thermal threshold.

The device is available in 10-pin MSOP (LY) and 16-pin TSSOP (LP) packages, both of which feature exposed heatsinks for enhanced heat dissipation. The packages are Pb-free and the leadframes are 100% matte tin.


  • The LED driver has a total current of up to 400 mA
  • The current is divided equally by 4 strings, each 100 mA
  • 6 to 50 V supply voltage
  • Low differential pressure
  • LED output short-circuit grounding and overtemperature protection
  • On/off toggle switch input
  • Enable PWM control inputs
  • Current slew rate during PWM
  • The current is set by a reference resistor
  • Automotive K temperature range (–40°C to 150°C): Please contact the factory for availability.
