This compact: high efficiency: 24V DC: 150W nominal: 240W peak output at 230VAC reference design is targeted for industrial AC/DC power supplies. The circuit consists of a frontend transition mode (TrM) power factor correction(PFC) circuit based on the UCC28056: followed by a robust LLC stage for an isolated DC/DC converter based on the UCC256301. For high efficiency needs: synchronous rectification is done with the UCC24624. This design does not need an additional auxiliary power supply to meet no-load consumption. The design enables 94% peak efficiency and allows the system to work without forced cooling. This design has both constant current(CC) and constant voltage(CV) feedback loop which is suitable for battery charger application.

This design uses the UCC28610 quasi-resonant flyback controller to generate 3 isolated outputs from an universal input (90VAC - 290VAC). It was built on a low cost single layer PCB. The regulated output provides 12V@1.89A and the maximum output power is 33W.

Low voltage brushed DC drives are used in many applications. TI offers a rich family of brushed DC motor driver solutions with flexible control interface options for one or more brushed DC motors up to 60V.  For applications which require higher torque and power: often voltages above 60VDC are used. The TIDA-00365 protected full-bridge operates at nominal 75VDC input and 10A output current and features bipolar high-side current sensing leveraging a 100V full-bridge gate driver SM72295 with integrated amplifiers and four 100V NexFET power MOSFETs with ultra-low gate charge and small SON5x6 package with low thermal resistance. The power stage is protected against over-temperature: over-current and short-circuit between the motor terminals and motor terminals to ground. Onboard power supplies provide a 12V and a 3.3V rail for the gate driver and signal chain. The host processor interface is 3.3V I/O to connect a host MCU like C2000 Piccolo MCU for brushed DC motor current control.

This reference design describes an 18W power supply for driving a string of 13 LEDs (3.3V) at 420mA. The targeted application for this design is T8 fixtures transitioning from standard fluorescent tubes to more efficient LEDs. With an operating efficiency of over 87%, an input voltage range of 90

Stepper drives are used in many applications operating typically from 12VDC to 48VDC. TI offers a rich family of stepper motor driver solutions with industry standard step/direction and parallel control interfaces. For applications which require higher torque and power: often voltages above 48VDC: up to 100VDC are used. The TIDA-00210 provides a solution for such stepper drives. The TIDA-00210 uses two protected full-bridge power stages based on TIDA-00365 in parallel configuration. Each full-bridge operates nominal 75VDC and 10Arms phase current and features bipolar high-side current sensing leveraging a 100V full-bridge gate driver SM72295 with integrated amplifiers and four 100V NexFET power MOSFETs with ultra-low gate charge and small SON5x6 package with low thermal resistance. The power stage is fully protected against over-temperature: over-current and short-circuit between the motor terminals and motor terminals to ground. Onboard power supplies provide a 12V and a 3.3V rail for the gate driver and signal chain. The host processor interface is 3.3V I/O to connect a host MCU like C2000 Piccolo for stepper motor control.
