TI reference design TIDA-00949 demonstrates a 15mmx20mm, 92% efficient low electromagnetic interference (EMI) DC/DC module using the TPS54202, replacing low dropout regulators (LDOs) in most appliance applications. High efficiency eliminates the need for a heat sink, resulting in a smaller, lower cost solution. Higher current capacity enables the addition of more functionality (WiFi, sensors, etc.). High efficiency and low current consumption help achieve stringent energy efficiency ratings.
REF_ICL8820_LED_43W_JT This 43 W reference design uses Infineon's high power factor flyback controller ICL8820. The evaluation board is a constant voltage (CV) secondary side regulation (SSR) system designed for use with a constant current (CC) converter for LED lighting applications.
Due to its simplicity and low cost, the flyback converter is the preferred choice for low-to-medium isolated DC-DC power-conversion applications. However, the use of an optocoupler or an auxiliary winding on the flyback transformer for voltage feedback across the isolation barrier increases the number of components and design complexity. The MAX17690 eliminates the need for an optocoupler or auxiliary transformer winding and achieves ±5% output voltage regulation over line, load, and temperature variations.
RDR-669 - 5 W, 85-265 VAC, Constant Voltage (CV) Adapter using LinkSwitch-CV (LNK625DG)
This design pairs the ultra-low-power MSP430 MCU with a sub-1GHz RF transceiver to achieve a battery-powered wireless sensor monitoring solution. This design demonstrates access points and wireless nodes that can share sensor data wirelessly using the network protocol "SimpliciTI". A PC-side GUI is also provided to visually display wireless data transmitted/received between various nodes and access points.
