General Description

The RT8480 is a current mode PWM controller designed to drive an external MOSFET for high current LED applications.

With a low side current sense amplifier threshold of 190mV, the LED current is programmable with one external current sense resistor.

With programmable operating frequency up to 800kHz, the external inductor and capacitors can be small while maintaining high frequency.

Key Features

  • High Voltage Capability : VIN Up to 36V, VOUT is limited by External MOSFET Switch.
  • Boost Operation.
  • Current Mode PWM with Programmable Switching Frequency.
  • Easy Dimming Control : Analog or Digital Converting to Analog with One External Capacitor.
  • True PWM Dimming : External FET Driver is Build- In.
  • Programmable Soft-Start to Avoid Inrush Current.
  • Programmable Over Voltage Protection.
  • VIN Under Voltage Lockout and Thermal Shutdown.
  • 16-Lead SOP Packag.
