The MAXREFDES1273 is a Power-over-Ethernet (PoE) powered device (PD) and an active clamp forward DC-DC converter (ACFC) that delivers up to 850mA at 48V from 39V to 57V supply voltage
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.
The MAXREFDES1171 uses Maxim® low-power chips for power grid fault indicators based on the low-power Arm® Cortex®-M4 processor.
TIDA-00679 TI reference design demonstrates a solution for automotive LED taillight applications (tail/brake lights, turn signals, reverse lights). This reference design uses the TPS92630 linear LED driver, which is powered directly from the car battery through a smart battery reverse diode. The design offers the potential for cost savings and efficiency through low power dissipation and improved system thermal performance. The reference design also includes CISPR25 testing, pulse testing (per ISO 7637-2), and EMI/EMC radiated and conducted emissions testing.

TI's TIDC-EVSE-WIFI validated reference design details how to implement a J1772-compliant Level 1 and Level 2 Electric Vehicle Service Equipment (EVSE) solution with added Wi-Fi® functionality. The CC3100 network processor allows highly embedded devices such as EVSE to easily connect to existing wireless networks or directly to the device. By integrating this functionality into the EVSE, the design enables remote power monitoring and control of the charge status of connected electric vehicles.
The PMP20410 is a synchronous 4-switch buck/boost converter reference design using the LM5175 controller for battery charger applications. Output voltages from 1V to 10V can be selected over a current range of 13A to 28A by using a trim resistor on the FB pin with a bias voltage of 0.2V to 3.1V. This reference design also uses the nonsynchronous boost regulator LMR62014 to provide bias voltage for the LM5175 operating in 2.7V input voltage mode. The current mode controller has built-in LM5175 pulse-by-pulse current limiting function. This board includes enable, sync, and power-good functions. This reference design supports resistive heating elements with resistances ranging from 0.1Ω to 0.5Ω, allowing 80W of power to be supplied.
