Reference Designs

  • TIDA-00782 Portable, High Brightness HD Projection Display Reference Design using DLP® Technology | TI.com
    TIDA-00782: This reference design, featuring the DLP Pico™ 0.45-inch WXGA display chipset enables use of HD resolution for projection display applications such as accessory projectors, smart projectors, mobile Smart TV, built in projectors like projection functionality inside notebooks, laptops and hot spots. The chipset used in the design comprises of DLP4501 (.45 WXGA) DMD and DLPC6401 display controller. The external LED Driver reference design can be accessed under following link: PMP4356
  • 25W, 100-264VAC Input, 0-10V Dimmable LED Driver for Downlights, Troffers and Modules
    PMP6023: This is an isolated, 25W, 0-10V dimmable LED driver design with >0.9 power factor (PF) which meets or exceeds commercial lighting PF and total harmonic distortion (THD) requirements. It is well suited for integral LED luminaires, or ballasts, that use high-brightness LED emitters. This design is optimized for a 500mA (max) LED output current and LED stack voltages ranging from 45 V to 55 V.
  • PMP4298A Direct Type and Local Dimming for Conventional TV power with an LED driver, no boost DC/DC | TI.com
  • PMP4298 Direct Type/ Local Dimming (Conventional TV power + Boost + LED driver) | TI.com
    PMP4298: In this topology, the UCC28051 is a boost transition mode (TM) power factor corrector (PFC), which can rectify an AC input line voltage to 380V DC; the resonant LLC stage UCC25600 regulates the output to 24V/2A for an audio amplifier with feedback to the LLC controller, and 48V for the LED driver input. The flyback with UCC28610 in parallel generates 5V/3A for the system board and 5V/1A for standby power. In the LED driver stage, the 48V input voltage requires another front end boost stage to boost the output voltage to 80V, which connects to the eight-channel TLC5960 with 20LEDs at 120mA per string.This technique is the most common type of current LED backlight; the LLC design is easily implemented. The intelligent headroom voltage monitor (oriHVM™) automatically minimizes the power loss caused by the LED forward voltage change. Only a single additional resistor regulates the boost dc-dc output voltage.
  • Dual-Channel Full-Bridge Converter (54V @ 30A) for PoE Power Sourcing (PSE)
    PMP6712: PMP6712 is a phase-shifted full-bridge converter capable of delivering 1600W of isolated output power and achieving efficiency of greater than 96%. This design uses the UCC28950 controller in a dual phase master-slave configuration. An LM5017 constant on-time synchronous buck regulator provides bias power to primary and secondary-side circuits using a coupled inductor with isolated flyback winding. The isolation voltage is specified as 2250VDC, allowing this design to be used as a system supply for Power Over Ethernet and other telecommunications applications.
