Differential Headphone amplifiers require positive and negative voltages. In this reference design, both voltages are generated from a single input voltage with an all integrated split-rail converter. It only requires one inductor and a minimal amount of external components to achieve a high effi

This reference design delivers a very low input voltage high current boost application with a combination of the TPS61088 and the TLV61220. The TLV61220 is a low-input voltage boost converter. Its minimum input voltage is 0.7V. Setting the TLV61220’s output voltage to 5.5V to supply the TPS

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

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.

The Sitara AM437x simplified power sequence feature provides flexibility to power designers. This reference design implementation is a BOM-optimized discrete power solution for the AM437x processor with a minimal number of discrete ICs and basic feature set. The solution represents a baseline of

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.

This design is a 20A Maximum Power Point Tracking (MPPT) solar charge controller created for solar panel inputs corresponding to 12V and 24V panels. The design is targeted for small and medium power solar charger solutions and is capable of operating with 12V/24V panels and 12V/24V batteries up to 20A output current. Designed with scalability in mind: it can easily be adapted to a 48V system by changing the MOSFETs to 100V rated parts. The user can also increase the current to 40A by using the TO-220 package version of same MOSFETs used currently. The Solar MPPT Charge Controller was created with real world considerations: including reverse battery protection and software programmable alarms and indications provided in hardware but were left non-configured. The design has an operating efficiency of above 97% at full load in a 24V system. For 12V systems the efficiency is above 96% and includes losses in the reverse battery protection MOSFETs.
