Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Hello Team,We have selected part no: LDK220 and LDK320 with a SOT-89 footprint for one of our applications. We have referred to the complete datasheet, but we have not found the test results for 5V output category devices, like the voltage dropout of...
I've been looking at the STEVAL-ISD01KCB, and I saw in an image that it has some capacitors between pins 8 (-DC) and 9 (+DC). What is the value of that capacitor? Is it necessary to include it? I ask because I've noticed that this capacitor slightly ...
I have design Buck converter with Viper318HD ,With below specification:Vin:(85 to 265)VACVout=12VDCIout=500mAAnd i not follow recommended Commponents value which Are mentioned in Edesign tool, i use components which are availble with me....
I have a design running on 24V SLA batteries using STEF01 fuses for protection of the lower powered rails and an LT4356 using external MOSFETs for a 25Amp rail. That 25A rail is giving me headaches. Staying within the SOA of the MOSFETs is not that e...
Hello, (L6562DTR)I have encountered some problems when using this chip and hope to get some suggestions from you； ”The PF output voltage of 480V FC load is 0.7435“ The power input voltage is 250V-528VAC, with PFC+ flyback. The PFC BUS voltage is 7...
Looking for datasheets for the STWBC2HP and STWLC89, do these exist? I can't find them anywhere on the internet
Hello Everybody, I'm new in this place. I use an Evalboard ISC005V1 with STUSB4500 and an dedicate MCU to manage I²C port. I wanted to change the configuration of the PDO3 from 20V to 15V. I select PORT3 ( write 3 in 0x70 register ) I configure DPM_R...
Hello ST community,I have two STEVAL-WBC86TX transmitter boards that appear to be locked. The boards still charge a phone when powered, but the I²C reset tool provided by ST cannot communicate with the main IC. I've tried FT260 recovery tool. I wo...
Hi, We have been testing our H-bridge on 2 EVALSTGAP2HDM with IPP026N10NF2S MOSFETs. The gate resistances are as per the EVAL board. We are seeing huge ringing on the gate signals for the low side FETs on both boards with no load connected. The high ...
I would like to identify the following two diodes, please.
