The MAX17504 high-efficiency, high-voltage, synchronously rectified step-down converter with dual integrated MOSFETs operates over a 4.5V to 60V input. The converter can deliver up to 3.5A and generates output voltage from 0.9V to 90% VIN. Built -in compensation across the output voltage range eliminates the need for external components. The feedback (FB) regulation is accurate to within ±1.1% over -40°C to +125°C. The devices are available in a compact (5mm x 5mm ) TQFN lead (Pb)- free package with an exposed pad. Simulation models are available. The MAX17504 features a peak-current-mode control architecture with a MODE feature that can be used to operate the device in pulse-width modulation (PWM) , pulse-frequency modulation (PFM), or discontinuous mode (DCM) control schemes.
The MAXREFDES1218 is an active-clamp forward power supply that delivers up to 4A at 24V from a 18V to 36V supply voltage. It is designed for industrial equipment that needs high power isolated power supply. The typical application of the MAXREFDES1218 is an IO-Link® application that needs a 24V isolated voltage from an industrial 24V supply voltage.

The PMP20612 reference design is a high efficiency AC-DC LED driver reference design with very low total harmonic distortion (THD). This design uses CCM PFC with the UCC28180 controller to provide power factor correction (PFC) functionality from 108VAC to 305VAC input. A two-switch Flyback converter with the UCC28740 controller is used to provide 200V/1A constant current (CC)/ constant voltage (CV). The voltage sensing and current sensing circuit at the output side with the TL431 and INA180 allow an external circuit to process a dimming function. As a result this design achieves 92.9% peak efficiency at 230VAC/50Hz input. At 277VAC, the board also has less than 20% THD with 20% load.

This document details the MAXREFDES128# subsystem reference design, a 36V to 57V input, 5V output, no-opto flyback isolated power supply capable of 12.5W. Design files and test results are included. Hardware is available for purchase.
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.
This TI design uses Hall sensing technology from Texas Instruments (TI) to provide a solution for understanding the AC current flowing through a wire without any physical intervention. The TIDA-00218 uses a flux concentrator to concentrate the magnetic flux around the AC current-carrying wire without allowing it to escape into the air, and then directs this magnetic flux to the Hall sensor.
