7.5W 5V Offline Flyback Converter Using the MAX17595
The evaluation kit supports the MC33879 device, an 8-output, hardware-configurable high-side/low-side switch that provides 16-bit serial input control.
The MAX16990 is a high-performance, current-mode PWM controller with 4μA (typ) shutdown current for wide input voltage range boost/SEPIC converters.
The MAX17595 is a peak-current-mode controller for designing wide input-voltage flyback regulators.
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 MAX1606 is a step-up DC-DC converter that contains a 0.5A internal power switch and a 0.5A output isolation switch in an 8-pin μMAX® package.
The MAX17595 is a peak-current-mode controller for designing wide input-voltage flyback regulators. The MAX17595 offers optimized input thresholds for universal input AC-DC converters and telecom DC-DC (36V to 72V input range) power supplies.
TI reference design TIDA-00946 demonstrates a 10.5mmx14.5mm, 94% 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.
The RD9Z1-638-12V is a battery management system (BMS) designed to demonstrate the capabilities of the MM9Z1J638 battery sensor module in 12 V lead-acid applications where high EMC performance is required to obtain high-precision measurements of critical battery parameters.
NXQ1TXH5 WPC 1.2 Compliant Wireless Charger Demo Board
TIDA-00940 is a 3W non-isolated bias power supply with up to 80% efficiency and excellent EMI performance, designed for motor control and drive subsystems in major appliances, saving system costs and having other features described here Main advantages. This reference design uses a buck topology to provide two non-isolated outputs, implemented using TI's UCC28881 and TPS5405 controllers, to provide comprehensive protection. The hardware is designed and tested to comply with EN-55014 Class B requirements for household appliances.
12V Offline Flyback Converter Using the MAX17595
The TIDA-00601 design uses isolated shunt sensors to implement a Class 0.5% three-phase energy metering system. Isolation is achieved by using an isolated Delta-Sigma modulator with a capacitively isolated output circuit. The energy metering SoC takes different bit streams from the isolated modulator and uses its onboard digital filter to generate ADC sample readings. The energy metering SoC is also used to sense voltages, calculate metering parameter values, drive the board LCD, and communicate with the PC GUI via the board's isolated RS-232 circuitry.
