The MAX17509 integrates two 3A internal switch step-down regulators with programmable features. The device can be configured as two single-phase, independent, 3A power supplies or as one dual-phase, single-output 6A power supply. It operates from a 4.5V to 16V input and generates independently adjustable output voltage in the ranges of 0.904V to 3.782V and 4.756V to 5.048V, with ±2% system accuracy. This device provides maximum flexibility to the end user by allowing one to choose multiple programmable options by connecting resistors to the configuration pins.
A SOT-223 packaged CoolMOS™ CE superjunction MOSFET (IPN60R3K4CE) (600V, 3.4Ω) is used as the main switch for this single-ended cap T8 LED lamp driver board with high line output and 16W/66V output converter. The converter uses ICL8201 (SOT23-6-1) to achieve average current controlled non-isolated single-stage buck topology in a cascade structure LED driver. Unique features of this reference design include single-stage design for high efficiency and power factor, single choke (no auxiliary winding) critical conduction operation, true regulated output current over a wide output voltage range, and excellent EMI performance and various protection modes for high reliability and small size that easily fits into a standard T8 LED lamp single-ended cap.

TIDA-00987 is a reference design for automotive media ports requiring data transmission. This design supports USB 2.0 and USB 3.0 data via the 15W USB Type-C™ port. Customers can accelerate their media port systems by leveraging a complete reference design that includes AEC-Q100 compliant CISPR 25 Category 5 tested analog integrated circuits (ICs). This design creates a reliable and flexible solution that allows the system to charge USB Type-C and legacy devices in a small 1 x 2.5-inch solution.
This reference design describes how to design hardware for a temperature-based heating system for a vehicle that has an engine preheater installed, based on ambient temperature and a preordained engine start time. This system can also be used for other purposes, such as turning on a storage heater if the ambient temperature falls below a preordained value.
This reference design implements a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors. This design uses the AMC1306E25 delta-sigma modulator for accurate shunt-based inline motor phase current sensing. The modulator output is Manchester encoded, simplifying clock and data signal routing between the MCU and the modulator. The modulator's high CMTI helps suppress inverter switching noise transients from causing data corruption on the controller side. A compact solution is achieved using a small size modulator. TIDA-00914 provides an interface to an external MCU or FPGA so that a SINC digital filter can be used to demodulate the AMC1306E25 output bit stream. This reference design uses the F28379D Delfino control card, which is connected to the card described in the reference design via an adapter card for current sensing using SINC filters.
The TIDA-01429 reference design uses a wide input voltage boost controller followed by a wide input voltage buck converter set to 5.0V. A 5.0V supply is used to power the controller area network (CAN) transceiver, and a compact 3.3V fixed-voltage linear dropout (LDO) regulator is used to power the C2000 microcontroller. This design has been tested for CISPR 25 radiated emissions according to the anechoic chamber (ALSE) method, CISPR 25 conducted emissions using the voltage method, and Bulk Current Injection (BCI) resistance according to ISO 11452-4, all tested at CAN communication operates at a speed of 500KBPS. This is an Electromagnetic Compatibility (EMC) tested, 3-level power tree reference design using Controller Area Network (CAN) that can be used in a variety of automotive applications that require operation at input voltages as low as 3.5V. A system basis chip (SBC) is an integrated circuit (IC) that combines several typical building blocks of a system, including transceivers, linear regulators, and switching regulators. While these integrated devices can provide size and cost savings in many applications, integrated devices do not work well in every situation. For applications that are less suitable for using an SBC, a better approach is to build discrete implementations of the above building blocks to create a discrete SBC.

However, an extra bias winding from the transformer is used to power the controller. This allows the input operating voltage to go up to 60V for this design.
