BTA16-800BW
Triac snubberless (bta-16-800bw) does not require a snubber in the circuit?Or would installing a snubber in the circuit have a good effect?The difference between BTA16-800BW and CW is the gate current difference.Will the current specification selecti...
Issue with ST1PS02 step-down converter
We are currently using the ST1PS02BQTR for powering a compact main board with BT connectivity (STM32WB5MMG), an IMU, and other ancillary blocks (LEDs, charge pump for LEDs, passives). The system is powered through two AAA batteries connected in serie...
Resolved! How to add the electronic load to the STEVAL-WLC38RX to simulate wireless charging of a smartphone
Hello everyone, to simulate wireless charging of a smartphone (I want to achieve 5W transmission to the load), I need to use an electronic load and add the load step by step. Since the wireless charging system cannot immediately absorb high current, ...
SMPS Pulsing in hiccup mode
Hello, I have designed and assembled a SMPS based on the EVAL-STCH03-45W evaluation board. What I have noticed, is that the power supply is outputting 1 Hz pulses with short buzzing sounds. These symptoms usually mean the hiccup mode is activated. Ho...
L4986 startup problems with external VCC supply
I am evaluating a PFC with the EVL4986-350W evaluation board.To be able to use Boost coils without the extra winding I want to supply the VCC voltage from a buck converter connected to the output voltage. The voltage from the buck is 17V.I have tried...
PowerSTEP01 - is the ResetDevice command conditional?
I have a PowerSTEP01 that is behaving unexpectedly when I send the ResetDevice command.If I send it when my system starts then everything is ok when I check the STATUS register.However, if I send ResetDevice after the motor has been moved (sequence e...
