General Description

The RT8485 is a current-mode PWM controller designed to drive an external MOSFET for high current LED applications.

With a current sense amplifier threshold of 315mV, the LED current is adjustable with one external current sense resistor.

With the maximum operating input voltage of 36V and output voltage up to 150V, the RT8485 is ideal for Buck, Boost or Buck-Boost operation.

Key Features

  • High Voltage Capability : VIN Up to 36V, LED Sensing Threshold Common Mode Voltage Up to 150V.
  • Buck, Boost or Buck-Boost Operation.
  • Adjustable Switching Frequency.
  • Easy Dimming Control : Analog or Digital Converting to Analog with One External Capacitor.
  • Adjustable Soft-Start to Avoid Inrush Current.
  • Adjustable Over-Voltage Protection.
  • VIN Under-Voltage Lockout and Thermal Shutdown.
  • RoHS Compliant and Halogen Free Ordering Information RT8485 Package Type.
