L6591 documentation issue regarding PWM nature

The datasheet notifies the the exact 50% Duty limitation because of using a T-flopflop that divides the oscillator frequency by two. Figure 48 (Oscillator waveforms and their relationship with gate-driving signals) suggests that each output would be ...

IGBT TO-247 Paralleling.

Evaluating STGW60V60F for a tractor-motor inverter project. Been using power modules but would like to switch to a TO-247 package. Your datasheet states "safe paralleling" for this device and "very tight parameter distribution resulting in safer para...

Where can I find the complete datasheet of STOD32A?

there is only the brief datasheet in STMicroelectronics websitewhich is not enough to add the STOD32A to any circuit.

I am looking for Reference code to generate 180 Deg phase shift PWMs for two phase interleaved synchronous buck converter. I am using STM8L152C8. If anyone can help on this. Thanks Manish

ST1S14 regulator start up issues during power ramp testing

Our product has the ST1S14PHR step-down regulator to supply 5V to the rest of the board. The input voltage range to the regulator is 8V to 24V, and the output is 5V at 1A max. We are seeing start up issues with the supply during power supply ramp tes...

I need example source code of SPI interface between stpm01 and STM8 MCU

SPV1050 behavior after UVP threshold

Hello,I would like to know what supposed to happen after the UVP threshold.During my test, I put a load at the LDO2 output and after the UVP threshold (Vbatt at 3.7V) I removed the load. After that, I put a solar pannel on Vin. I don't know why but t...

Issue with starting VIPer35 flyback

I'm facing a strange situation with VIPer35. First, I bought STEVAL-ISA183V1 evaluation board to got an idea how VIPer35 works. Then I made my first prototype PCB using custom made transformer that also works fine. But when I use the same schematic (...
