TIDA-01234 24W Boost and Boost-to-Battery Reference Design for Automotive LED Lighting | TI.com
TIDA-01234: TIDA-01234 is a 24W, high-efficiency (94%), low cost, Asynchronous boost design for automotive LED application based on LM3481-Q1. This design applies to automotive high brightness lighting such as headlights and taillights and also interior LED lighting systems. It is designed to operate with an input range from 6Vin to 18Vin and can drive multiple strings of 6 to 7 LEDS (16V to 24V) in series at 1A constant current. The design support analog LED brightness control and output open protection. In Boost-to-Battery configuration, input voltage can either be higher, lower or equal to required LED strings voltage.

TIDA-00744 50W System-Level Power Reference Design for Automotive Infotainment Systems | TI.com
TIDA-00744: TIDA-00744 is a 50-W system-level SMPS design for mid-power automotive infotainment systems. The design has protections, such as load dump through TVS (ISO pulse testing), as well as reverse voltage (innovative smart diode with very low Iq) protection. Furthermore, all the controllers (boost and dual bucks) are in SYNC for EMI-optimized design. The design is divided into four major blocks:
LM3481-REF 330mW AC or DC Tiny Flyback Converter Power Supply Reference Design | TI.com
LM3481-REF: The main purpose of the power supply is to convert the rectified AC Input to DC regulated current for 6 LEDs. The power supply provides protection for the LEDs, limits the transient input voltage and protect against inrush current at plug in. The overall power supply conformity (e.g. mains harmonics (EN), mains interference, international safety standards etc.) are not approved for all the applicable European Norms (EN). This application note describes the design of a tiny AC or DC Flyback power supply. It�s main purpose is to convert the rectified AC or DC Input to DC regulated output voltage. The power supply provides protection for this supply voltage, isolates the rest of the network from the output, limits the transient input voltage and protects against inrush current at plug in. The board fully complies to the EN55022 norm (Conductive average) and international safety standards. The secondary side is regulated at 3.3V. The controller is switching with a fixed frequency of 250 kHz. The heart of the power supply is the controller LM3481 current mode PWM from National Semiconductor. The advantage of the proposed solution is using a standard off the shelf transformer, small solution size and high ambient operating temperature up to 85�C (105�C possible). Based on the presented solution higher output power up to several Watt can also be achieved using the LM3481.
PMP40100 Isolated Multi-rail Output Flyback Reference Designs for HEV/EV Battery Management Systems | TI.com
PMP40100: The PMP40100 is an isolated flyback solution which accepts an input voltage of 5V to 36V and provides multiple 3KV isolated output rails to the load. The reference design is set up for 15V at 100mA, and 6V rails at 300mA each. The reference design features good line and load regulation and good thermal performance. The design also integrates the transformer winding within the PCB which significantly reduces the PCB board makes it easier to integrate into a system board.
