Part Details for SN74ALVC244 by Texas Instruments

其为非同步降压控制器。其采用恒准时 (COT) 器件，即 LM5085。该电路采用具有极低 ESR 的陶瓷输出电容器。因此，纹波是由电感器的 DCR 产生的。所以，纹波电压叠加在反馈电压上。

This reference design is a 4-kW interleaved CCM totem pole (TTPL) bridgeless PFC reference design using a 64-pin C2000™ microcontroller: LM3410 gallium nitride device and TMCS1100 hall sensor. It is based on TIDM-02008 bidirectional interleaved CCM TTPL bridgeless PFC reference design using C2000™ MCU : and reduces the dimension of the total PCB to 145 mm by 105 mm by 35 mm. Gallium nitride (GaN) devices are used in power stage: achieving peak 98.73 % efficiency. The design includes advanced functions such as phase shedding: adaptive dead time: input cap compensation to improve PF and efficiency on the load range: and non-linear voltage loop to reduce the voltage overshoot and undershoot under load transient.

This SEPIC converter provides a regulated 48V output from a 40V – 60V input and achieves efficiency greater than 92%. Possible applications include wireless, telecom and industrial.

The DesignDRIVE Development Kit is a reference design for a complete industrial drive directly connecting to a three phase ACI or PMSM motor. Many drive topologies can be created from the combined control: power and communications technologies included on this single platform.  Includes multiple position sensor interfaces: diverse current sensing techniques: hot-side partitioning options and expansion for safety and industrial Ethernet.

This design implements a network camera with a QVGA display panel and an embedded web server for remote monitoring.  With a memory footrpint of 250KB for the web server: there is ample memory available on the TM4C129x microcontroller for additional customizations.
