Two-Phase Interleaved Power Factor Correction Converter with Power Consumption Metering

This design is a digitally controlled two-phase interleaved 700W power factor correction converter with added power metering capabilities. The power factor correction converter's two 180° phase-shifted boost power stages use a C2000™ Piccolo™ microcontroller, which also monitors line and neutral voltage waveforms for power metering functions. This design is able to achieve 97% efficiency and 1.5% THD (full load) with a power factor greater than 0.98. This design is an excellent choice for offline applications and AC/DC power supplies by minimizing power losses in the power stage, mitigating the reliability impact of harmonic distortion, and providing near-peak power factors.

High-brightness single LED driver reference design for 1 to 2 AA battery applications

This reference design uses the boost converter TPS61021A to provide a high-efficiency LED driver circuit with dimming capabilities. The PWM dimming method can be used for one or two AA battery input applications, while the analog dimming method can be used for one AA battery input application. The PMP15037 enables dimming functionality by adding multiple resistors and a MOSFET to the circuit, making it a cost-effective and efficient solution for LED driver applications.

Low voltage brushed motor system

This brushed motor system uses an MSP430 microcontroller, a DRV8837 brushed DC motor driver, and a 12V brushed motor. This system is suitable for applications requiring speeds up to 10,300 RPM under no load conditions. The system measures 19 x 33 mm without motor, making it ideal for applications requiring a small footprint. The motor power supply voltage supports 1.8V to 11V, and the maximum current is 1.8A. There are various configuration options for easily controlling the rotation of the motor, changing the direction of rotation, and placing the system into a low-power state to reduce energy consumption when not in use. The motor drive platform incorporates protection against short circuit, breakdown, undervoltage and overheating.
