We need help for SMPS design using l6566b
Posted on June 02, 2017 at 10:01We developed SMPS using L6566b reference from ST power supply tool.Designed for 90-450Ac to 12vdc/2Amps.We observed that get output voltage of 11.73Vdc load of 8 ohm but no load condition get 11.90Volts.Above reading ...
STPM34 problems with phase-angle measurement
Posted on June 01, 2017 at 10:27Hello. I'm working with stpm34 and have a next problem. I can't get phase-angle measurement. It's always zero. I've got period measurement and it work well. I checked PER_ERR, but it's odd. It's placed in two position...

Posted on May 30, 2017 at 16:32Hi all,I have a device which works with 2 pcs Li-Ion battery 18650 each 3.7V in serie and need 5V and 3.3V each 500ma.I want that the device has a 12VDC standard power connection and when the power is connected, the de...
Resolved! I'm looking for a spatial component
Posted on May 30, 2017 at 09:13Hi, I'm looking for a spatial component (ESA qualified would be better) which is equivalent to an Eight Darlington Array like the series ULQ280X. Thank you ! Have a nice day !
Hello! I'm workng on a proect of smart meter using stpm34.
Posted on May 29, 2017 at 18:01My question ask is related to the following: If I send by my code to the stpm34 consecutively dummy commands 0xffffffff,will the read pointer for read register increment, for example if I send command 0x30ffffff and af...
Shifted PWM generation
Posted on May 29, 2017 at 10:17I need to generate two PWM signals (frequency 6.78MHz, duty cycle 50%) to drive an inverter that must be shifted by an amount programmable on-line by the user (the chip will be interfaced with a microcontroller and mus...
