EVALSTPM34 boards work unstable when using single Clock source
Hello, I am trying out a 220 V power measurement set up with 3 STPM34 evaluation boards. I need to use as less wires as possible, so I am using SPI with 3 different CS and 1 SYN pin. I am also trying to reduce component count by using only 1 CLK sour...
Resolved! L6902 component choice
Hi, I'm designing a DIY switching power supply around the L6902. Intended output voltage is <22V, input voltage 24V, output current in constant current mode between 0.6 and 0.8A.My questions:the datasheet shows an inductor value of 22uH, is this valu...
Getting started with the STDES-30KWVRECT 30 kW Vienna PFC rectifier reference design UM3011
I am working on Vienna PFC rectifier and was studying ST Microelectronics application note UM3011.In the note equn. (9) is given as while my working on these equations I got following results If someone can go through my derivations in attached file ...
Resolved! Using MPP on stwlc38
Is it possible to use a Qi2 rx coil with magnetic array on a stwlc38 design? The goal is to use a Qi2 charger and reap the benefits of magnetic alignment and 15W charging while still being on the Qi1.3 standard of the stwlc38.
ST Motor Control Workbench "PDSC version is not supported"
Hi, I am currently working on a project that uses a BLDC motor (42BL90L2-3), and I am trying to drive it using a DRV8323 gate driver. I have been using the ST MC workbench (version 5.4.8) to profile the motor and control unit, but when I try to gener...
Viper06LS shuts down over 520 VDC Input Voltage
Hello,I use the Viper06LS in the Buck Converter topology.The input voltage can vary between 100V and 530VDC. The output voltage is regulated to 10 V. (See "Viper_circuit"!)Unfortunately, a problem arises when the input voltage increases to approx. 52...
STC3115 SoC indicates 100% too soon while charging - Detailed Post
Hi all,We're using the STC3115 for a single-cell lithium battery, the main goal is to provide a SoC that gives the user a feeling about remaining battery life.This is working quite well when we're draining the battery completely, even in very differe...
UC3845 Mosfet driver IC can support Non isolated converter?
Dear Engineers pls comment on my Querys.... Is it possible for UC3845 Mosfet driver IC to accommodate non-isolated converters? Additionally, could you please clarify which can control MOSFET switches in a Buck converter?
Resolved! Capacitor at The AUX
Hi, i design a SPMS with VIPER013HS and in the design schematic, i dont know the purpose of the capacitor in attached picture. Also in design, there is no capacitor value mentioned for this capacitor.
L6235
Hi I want to use a L6235 to control a BLDC motor, but do not have a micro to control the loop. Micro not an option. The are two options I have is to use an integrator as per datasheet or use app note DT0001 mention using the Tacho output and the FWD...
