15W 24V Offline Flyback Converter Using the MAX17595
LSM6DSL adapter board for standard DIL24 sockets
The PMP10748 is a complete automotive front-end protection TIDesign featuring TI's Zero IQ smart diode controller and high-side protection controller. This design utilizes two LM74610-Q1 ICs to drive 40V MOSFETs in an OR-ing configuration to provide reverse polarity protection. The LM74610-Q1 is a high-efficiency, zero-IQ alternative to lossy diode and inefficient PFET solutions, providing reverse polarity protection. The design also provides programmable OVP, UVLO and OCP through the LM5060-Q1 high-side protection controller. With the LM5060-Q1, this design not only has controllable rise time for safe connections, but also has programmable fault detection delay time.
This reference design shows how to use a MAX15005 automotive power-supply controller as a boost circuit to maintain a constant voltage during an automotive cold-crank condition.

TIDA-00675 reduces power consumption by using load switches to dynamically turn loads on/off. The design guide explains how switching frequency, duty cycle, and the use of discharge resistors affect power dissipation.
This document details the MAXREFDES119# subsystem reference design, a 17V to 36V input, 5V output, no-opto flyback isolated power supply capable of 9W. 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.
This document details the MAXREFDES111# subsystem reference design, an 18V to 36V input, 5V/2W output, flyback isolated power supply. Design files and test results are included. Hardware is available for purchase.
The TIDA-00486 TI design uses Texas Instruments' SimpleLink Wi-Fi CC3200 on-chip Internet wireless MCU module to create a data bridge between an RS-485 network and a Wi-Fi network. The ISO15 transceiver provides an isolated RS-485 interface with electrical isolation up to 2500 VRMS. The LM5160 Fly-Buck™ power supply provides both isolated and non-isolated 3.3V outputs for both parts of the circuit. This design can be powered by AC or DC supplies up to 30VRMS or 48V peak. A version of this design with a non-isolated RS-485 interface is included in TIDA-00485.
This reference design is a 120Vac to 17V flyback converter with synchronous rectification on the secondary side. A lossless passive clamp on the primary side helps this reference design achieve greater than 93% maximum load efficiency. When combined with the PMP20172, this reference design becomes a complete solution for a 36W USB Type-C dual-port solution.
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.
The MAXREFDES1214 is a portable USB charger that uses a lithium-ion (Li+) battery to charge a USB device from a USB Standard-A connector.
Power over Ethernet (PoE) is a technology that allows network cables to deliver power to a powered device (PD) through power-sourcing equipment (PSE) or midspan, and has many advantages over traditional methods of delivering power.
This reference design provides application circuit and simulation examples of the TPD7106F, whose features include power supply reverse connection, charge pump circuit, etc.
