85VAC-264VAC Input, 55V/2A QR Flyback + PFC
PMP6910: The PMP6910 reference design delivers an isolated 55V at 2A with PFC from a universal AC input. This design is a modified version of the UCC28600 EVM. The PFC boost portion of the design is unchanged from the original EVM. The UCC28600 quasi-resonant flyback has been modified for the higher output voltage. The flyback portion of the design is over 88% efficient. The total input-to-output effciency of the design is 83% from a 120VAC input and 85% from a 240VAC input. For sustained loads over 1.5A, forced air cooling is recommended.
Three-Phase BLDC / PMSM Motor Drive with High-Performance Microcontrollers Reference Design
TIDM-RM46XDRV8301KIT: This TI design describes a motor control evaluation kit for spinning 3-phase brushless DC and brushless AC (BLAC) - often referred to as permanent magnet synchronous (PMSM) – motors with example of sensorless Field Oriented / Vector Control (FOC). The implementation leverages the DRV8301 gate-driver IC as well as the TPS65381 Power-Management IC. This reference design can be used as a high-performance, power-efficient, cost-effective platform to speed up development of PMSM control algorithms.
16-bit 400KSPS 4-Ch. Multiplexed Data Acquisition Ref Design for High Voltage Inputs, Low Distortion
TIPD151: This TI Verified Design implements a 16-bit, differential 4-channel multiplexed data acquisition system at 400KSPS throughput for high voltage differential input of ±20 V (40 Vpk-pk) industrial applications. The circuit is realized with a 16-bit successive-approximation-resistor (SAR) analog-to-digital converter (ADC), a precision high voltage signal conditioning front end, and a 4-channel differential multiplexer (MUX). The design details the process for optimizing the precision high voltage front end drive circuit using the OPA192 and OPA140 to achieve excellent dynamic performance with the ADS8864.
