Reference Designs

  • PMP10725 Multiport Isolated Output Flyback Solution Reference Design Featuring the LM3481 | TI.com
    PMP10725: PMP10725 is an isolated flyback solution which accepts an input voltage of 15 to 36VIN and provides multiport output to the load. This reference design compares primary and secondary control solutions. With primary control, it can achieve higher efficiency with lower BOM cost, but the regulation performance is not so good. With secondary control, it can achieve great load regulation performance by controlling the 24V-rail voltage. This LM3481 flyback reference design can be used for supplying the digital output module in industrial PLC application.
  • PMP8917 High Efficiency Synchronous Flyback with 36-72Vin to 5Vout@2A Reference Design | TI.com

Transient mode (TM) power factor correction (PFC) with UCC28051 and LLC series resonant converter (SRC) with UCC25600 are applied in PMP8911. Low EMI is expected with zero voltage switching on TM-PFC and LLC-SRC switches. An overall 92% efficiency is achieved at 100W full load. In addition, several protections are embedded into this design which includes input under-voltage protection, input over-voltage protection, output over-voltage protection, and output hic-cup over-power protection.
  • PMP15012 Inverting Buck-Boost Reference Design Featuring LMR16020 DC/DC Buck Converter | TI.com

  • ISOLOWNOISESPLITRAILGEN-REF ± 5V Isolated, Low Noise Split Rail Generator (0.25A, 2.5W total) | TI.com
    ISOLOWNOISESPLITRAILGEN-REF: A very low noise differential power supply for split rail systems requiring low noise +5V and -5V (higher or lower voltage is possible). This design is fully isolated and capable of floating to over 500V differential from Vin to Vout (higher is possible). The LM5001 IC is a fully integrated flyback regulator which performs all of the current mode control for tight regulation and transient response. The design is small and uses only one side of a double sided FR4 PCB for components. Smaller IC packages are available so the layout can be further optimized. This design provides very low noise bias rails for ground referenced analog circuitry (under 20 mV p-p total noise up to 1GHz). The design utilizes a very small size PCB footprint. This approach is ideal for many applications including low noise cable drivers, medical electronics, high fidelity low power audio, and other sensitive circuitry that can benefit from very low noise split rail biasing. Input to output isolation is employed for those applications where the input and output voltages might be at different potentials or when the input voltage travels across cabling which might pickup noise. The floating outputs avoid unwanted ground currents and the potential for additional noise pickup. For those that do not require isolation they can remove the feedback isolation section of the design and use a simple resistor divider for setting the feedback voltage.

    PMP9739: The PMP9739 is a single stage LLC series resonant converter (SRC), producing up to a 250W output using UCC25600 resonant controller. With the use of single stage LLC-SRC, the converter efficiency goes up to 89% at 250W full output power.
  • High-Eff 2Stage Univ Input Pwr Supply Using Trans Mode PFC/LLC Resonant Conv Reference Design
    PMP8920: Low EMI, high efficiency, high power factor and reliable power supply are main focus of the PMP8920 design for telecom applications. Transient mode (TM) power factor correction (PFC) with UCC28051 and LLC series resonant converter (SRC) with UCC25600 are applied in PMP8911. In addition, synchronous rectifier (SR) IC UCC24610 is applied to LLC output rectifier stage. Low EMI is expected with zero voltage switching on TM-PFC and LLC-SRC switches. An overall 91% efficiency is achieved at 100W full load. In addition, several protections are embedded into this design which includes input under-voltage protection, input over-voltage protection, output over-voltage protection, and output hic-cup over-power protection.
