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...
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 ...
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.
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...
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...
Hi,I use the STWLC38 for wireless charging.Just set the BPP VOUT to 9V, and other REG is in default value.In test , the output current around 0.6A . (The chip emits a squealing sound)If I want to set the Rx to 15W, which REG I need to set. And I have...
I had previously asked in case # 00204067, if the subject part STGF15H60DF was UL approved for isolation and I was told that is was approved under UL catigory QQQX2.E81734 per the requirements of UL 1557. I was linked to UL File # E81734 with a highl...
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...
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?
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.
