Posted on May 09, 2018 at 01:29There is some contradiction about STPM32/33/34 POR initialization:'After POR, to ensure a correct initialization, it is necessary to perform a reset of DSP and communication peripherals through three SYN pulses (see Se...
Posted on June 28, 2018 at 16:31I'm trying to get the battery detection feature to work on this board. The spec sheets and user manuals are somewhat lacking on this information. I've played around with the board a bit, but to no avail. Here's the co...
Posted on June 28, 2018 at 10:24Hi?I use the L6563S to design a 200W DC power.I just wanted to know how the L6563s to start working .I don't know the effect of diode D0 betweeninductanceT1 and capacitorC0.What it needs to work normally form the sta...
Posted on June 27, 2018 at 12:26Hi,I've almost completed the design of a 150W 35-60V Input and +15 / -15V Output DC-DC LLC resonant converter using L6599. On the secondary side I have a center tapped winding configured across a full bridge to delive...
Posted on June 27, 2018 at 01:31Hi all, is it possible to use multiple (3-4pcs) SPV1040 parallel on the input side for a low voltage high current solar solution?Will the MPPT still work fine?
Posted on June 26, 2018 at 08:28I have been evaluating ACST1235 for AC switching and need help to find the optimal driver for connecting it to a micro-controller (3.3V) with galvanic isolation.I have tested ACST1235 with MOC3023 and FOD4208 optocoup...
Posted on June 25, 2018 at 16:25Hello all,I have a question regarding the EV-VNH7040AY DC motor controller evaluation board. In the package it is included with the board a 1K? resistor that I have no idea what it is for. My guess is that is has to d...
