| Topology | Flyback Converter |
| Input voltage | 90-277 V |
| Output 1 | 48 V / 0.4 A |
| IC revision | 1.0 |
Description
The ICL8105 universal evaluation board is designed to offer designers maximum flexibility in terms of design during the initial design phase. It provides a flexible base for evaluating the performance of the ICL8105. Theobjective of this board is to allow the designer a faster way to finalize the circuitry and component values before designing the form factor PCB. By default, it is configured as a single-stage PFC flyback topology.Tuning of power factor (PF), total harmonic distortion (THD) and electromagnetic interference (EMI) is possible with the adjustable input/output capacitance and the option of using different line filters.The controller provides the ability to use different transformers, allowing easy adaptation for different power applications (20 W, 40 W, 60 W and 80 W). The availability of different footprints of the MOSFET andoutput diode allows the designer to choose the most cost-effective solution.The output voltage can be tuned by enabling/disabling the VCC voltage regulator circuitry. Synchronous rectification circuitry is available for selection in the case of high-efficiency applications. Designers canchoose to use an active or passive output bleeder to support hot-plug of LEDs and to protect LEDs against overvoltage when being reconnected.Current (IVcc, Ipri, Isec) can be measured easily across a jumper. Test pins are placed in strategic points for easy hook-up with oscilloscope probes for testing and measurement.
