Product Overview

The UCC28810EVM-002 is a constant current non isolated power supply for LED lighting applications. It will convert universal mains (90VRMS to 264VRMS) to a 0.9A constant current into a 100W load. This evaluation module will allow the customer evaluate the UCC28810/11 in a typical LED lighting application. The evaluation module uses a two stage approach to controlling the output current. The first stage is a transition mode PFC circuit. This ensures the design meets the harmonic current or power factor requirements set out by various standards, such as EN61000-3-2. The PFC circuit converts the AC input to a regulated DC voltage. The boost follower PFC is where the PFC regulated output DC voltage tracks the AC input peak voltage. The second stage also uses transition mode but is configured as a buck converter. It converts the PFC output voltage to a fixed constant current. This circuit is capable of supplying 0.9A into a 100W load. It also accepts PWM dimming inputs.
  • 90VRMS to 264VRMS operation
  • Boost follower or fixed output PFC stage
  • PFC disable
  • Output current disable
  • External or internal PWM dimming
High voltage may cause injury. Please ensure all safety procedures are followed while working.
