Telecom hot-swap reference design effectively solves the problem of instantaneous input overvoltage and power outage

This 80W telecom hot-swap reference design is immune to 150V input-voltage transients and 16ms power dropouts. Additional features include -32V to -72V operation, two-diode OR-ing input, and an inrush current that is ≤ 1.5 times the full -load current. Included are a detailed schematic, representative PCB layout, bill of materials, waveforms detailing actual performance at startup, -150V input transient, and full-load holdup at power loss.

Basic simulation circuit of flyback AC-DC power supply

MAXREFDES1107: Small-footprint, 12V/1A, synchronous, optocouplerless flyback DC-DC converter with 92.8% efficiency using the MAX17690 and MAX17606

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.

MAXREFDES1017: Optional single-output SEPIC converter

The MAX16990 is a high-performance, current-mode PWM controller with 4μA (typ) shutdown current for wide input voltage range boost/SEPIC converters.

5V 1A, low EMI, 94% efficiency DC/DC module reference design using double-layer TO-220 package

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.

KITFS5600FRDMEVM: FS5600 Evaluation Board

MAXREFDES1086: 91.4% Efficient Small Form Factor, 5V/500mA, Synchronous, Optocouplerless, Flyback DC-DC Converter

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.

MAXREFDES1018: Boost single-output DC-DC converter, 1V to 3.3V input, 13.5V/6mA output

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.

Multiphase Energy Measurement Reference Design Using Isolated Shunt Sensors

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.
