This reference design is a high efficiency, high power density and light weight resonant converter reference design. It converts a 390V input to a 48V/1kW output. The PMP20637 power stage has over 140W/in^3 power density. The whole board weight is less than 210g. With fixed 950kHz switching frequency in steady state, 97.6% peak efficiency is achieved.
This evaluation kit supports the fully integrated MC34717EP Dual Switch-Mode Power Supply—a dual-synchronous, buck-switching regulator.
This reference design delivers an accurate output current limit solution for the TPS61088 boost converter. This feature is realized by an output current sense resistor and a low cost operational amplifier. When the output current is higher than the current limit point, the output of the operational amplifier will be higher than the TPS61088’s 1.204V reference voltage. So the output voltage drops. If the output current continuously increases, the output voltage will be further decreased. Thus the maximum output power will always be limited below a certain level.
The PMP15007 uses the LM5161-Q1 in Fly-Buck topology with both primary and secondary output voltages set to 5V nominal. This circuit can accommodate a voltage input range of 36V to 72V, making it ideal for a 48V nominal input voltage rail. The primary side is set to 5.32V nominal and the secondary isolation side is 5V with feedback resistors and is based on Coilcraft LPD8035V series coupled inductors set to a 1:1 turns ratio. The maximum operating current is set to 225mA on both the primary and secondary voltage rails. The switching frequency is set to 315kHz nominal.

This TI Precision Verified Design provides the principles, component selection, simulation, PCB design and measurement details for a single-ended input of a specific differential output circuit that converts a single-ended input from +0.1V to +2.4V ±2.3V differential output on a single +2.7V supply. The output range is specifically limited to maximize its linearity. This circuit consists of 2 amplifiers. An amplifier acts as a buffer, creating the voltage Vout+. The second amplifier inverts the input and increases the reference voltage to produce Vout-. Both Vout+ and Vout- range from 0.1V to 2.4V. The voltage difference Vdiff is the difference between Vout+ and Vout-. This will give a differential output voltage range of +2.3V.

This verification design utilizes a triangle wave generator and comparator to generate a pulse-width modulated (PWM) waveform with a duty cycle that is inversely proportional to the input voltage. The op amp and comparator generate a triangular waveform, which is then passed to one input of the comparator. By passing the input voltage to the other comparator inputs, a PWM waveform is generated. Negative feedback from the PWM waveform to the error amplifier is used to ensure high accuracy and linearity of the output. This design was constructed using the OPA2365 op amp, TLV3502 comparator, and REF3325 reference. Learn more about TI's high-precision designs

6 W isolated flyback power supply with lossless generation of AC zero-crossing signal using LinkSwitch-TNZ (LNK3306D)
The TIDA-00912 TI reference design provides a complete isolated current measurement reference solution using an external shunt, reinforced isolation amplifier, and isolated power supply. Parallel voltage is limited to 25mV. This reduces power dissipation in parallel connection, enabling high current measurement ranges up to 200A. The shunt voltage is amplified by an instrumentation amplifier configuration with a gain of 10 to match the isolation amplifier input range for better signal-to-noise ratio. The output of the isolation amplifier is level shifted and adjusted to match the full input range of the 3.3V ADC. This design uses a free-running transformer driver operating at 410kHz to generate an isolated supply voltage in a small form factor to power the high-voltage side of the circuit.
