Power management

We have a requirement to design a AC to DC Converter with the following specification, VAC input (180-276VAC),Output 24VDC/6A,with current limit 7.5A. I planned to go with forward converter pls suggest any reference design from ST.

Hi, I am working on the stusb1702 device. I downloaded the datasheet but informations are missing. As software ingineer i am interested about the detail of register. Can I have a project example using the stusb1702 in sink role. Sincerely, Paul-Emile

How to drive triac with negative power supply

Hi Everyone, this is my first post here.I am trying to drive a triac BT134 directly from the ATTiny816 processor. The goal is to drive the triac in Quadtrant 2 and 3. I have referred to the note by ST for negative power supply. Please see attached im...

Hello I would like to get guidance on the design of MCU based 3 phase and single phase voltage monitoring(read energies, phase and line voltage, power factor, frequencies)

L6599 or L6699 as Full Bridge controller?

Hi,I am already using the L6599 as a HB LLC controller and I am trying to achieve higher output powers, however my input supply voltage is only ~30V. Already primary side currents are high. In order to bring these to realistic levels I really should ...

L6480 when in run mode I changed direction of the motor. But when its effected after a delay near to 750 ms what may be the reson. When I am trying with another motor with another settings the delay is reduced. Can any one explain the cause ?

What could cause the output of an LD1117 Voltage Regulator to increase above its specification?

My design is using an LD1117S33CTR voltage regulator. I am experience some rather odd behaviour where the regulators output is actually increasing from the expected 3.3V all the way up to 4V. What could cause such behaviour? I am stumped.

Problem with pin status after power on

Hi, I am solving the backlight of the display, which is controlled by a pin, but the problem is the state between power on and initialization, when the display flashes before the pin is initialized. This happens with both positive and negative contro...
