Why RC snubber is not recommended for the diode in the secondary output
I am using Viper27HD integrated circuit. RC snubber structure is not recommended for the diode in the secondary output on the datasheet and edesignsuite.Resonance occurs between the secondary leakage inductance of the transformer and the parasitic ca...
Viper115 cannot produce the required current
I am designing a new SMPS for my project I need 350mA at 15V but I could not get more than 100ma. when I reach to 100mA output voltage was start to decrease. when current goes to 200mA, output is like a sinusodial signal from 9v to 15V. I design my S...
TCPP01-M12 OVP on CC lines
Good morning, I have got a couple quick questions about the TCPP01-M12 chip:Does the OVP protection on CC lines works passively? (no voltage on VCC pin) I am talking about connecting/disconnecting USB plug conditions.What happens when there is perman...
EVLVIPGAN100PD
I've encountered an issue while simulating a schematic in the eDsim software. I attempted to create a schematic resembling the reference design by exporting the schematic of a 100W flyback converter from the online tool of ST eDesign suite. I then ma...
Resolved! VNF9Q20F Grounding
From the application schematics of VNF9Q20F, seperating my ground planes for CReg and DVcc but wouldnt DEV_GND (straight from the VNF9Q20F at the bottom) be connected as well instead of to battery ground? Shown as the drawn orange connection. Or both...
Resolved! Power Path Selector with STMPS2141STR
Hello everyone, I am designing a PCB and I want a power path selector which can change the source between USB and Battery.Can I do this with STMPS2141STR ? I cannot find a circuit or an application note. This is my design is that correct ? Can someb...
Re: STWBC86 -> Writing FTP (Few Times Programmable) from header over i2c?
@saleh1000, There is no mention on how to actually perform writes to the FTP (Few Times Programmable) memory in the Data Sheet.
Resolved! STWBC86 -> Writing FTP (Few Times Programmable) from header over i2c?
Hello, Looking through the data sheet for the STWBC86, there doesn't appear to be a way to write to the FTP (Few Times Programmable) memory, nor save individual configuration register values over i2c. Any register values are only written to RAM and ...
