Resolved! HVLED007
Hello, Good Morning Can i design SMPS using HVLED007 which should work on universal input and should provide 24v 2amp at its output it is PFC too. The most challenging part is to calculate and wind flyback transformer. I've some transformer bobbins a...
STPMIC25APQR LDO Programming Issue
Hello We are currently working on programming the STPMIC25APQR Power Management IC and are facing some issues related to the LDOs.As per the datasheet, there are no NVM control registers for LDO1 and LDO4, with their default output voltages specified...
Resolved! L9396 VBST overvoltage
Hi team, I have a question about L9396 VBST and VB voltage. The normal operation voltage rage of VBST and VB pin is (-0.1V,19V), and the absolute maxmum ratings of VBST and VB pin is (-0.3V,40V). So, in case that the voltage is (19V, 40V), what will...
STNS01 - battery greater than supplied Fast Charge current
Hi I'm using the part STNS01 with a Li-Polymer batter of 6mAh (nominal capacity).. I've used a 13KΩ resistor for to set current charge limit which provides 15mA as the output for the CCCV charging. Would there be any issue with using a 6mA batte...
BTA40-600B, optocoupler and snubber
I intend to design a microcontroller circuit with a BTA40-600B RD91 to control the power delivered to a heating resistor (220Vrms, 12Ω, 4KW). I thought about using the MOC3023 to mediate the activation of the BTA40, but I don't know if it is the most...
C source code for STSW-3KWTLCP
Hello and nice dayI am looking for STSW-3KWTLCP source code.As you know, the .bin and .out files are uploaded on the product page, these files are definitely obtained from the codes which written in C language, I would like to know how I can access t...
Resolved! LDO29300P2MTR
We have implemented the following circuit. This matches the application circuit given in datasheet of LDO29300P2MTR.But it does not yield expected output. We need help!!
WLC38 - compatible chargers
Hi,We are developing a product using the WLC38 as RX.It works OK in combination with wbc2tx50 board, and a single Spigen QI charger we found (no overheating, constant power > 10W achievable).However using any other charging pads (either Qi1 15W or Qi...
L99DZ100G Out1 to Out6 remains High by default.
I am working on L99DZ100G IC. I am able to communicate with L99DZ100G correctly. But when I check Out1 to Out6 , I am getting 12V by default. If I make on and off CR4.B.OUT1_HS and CR4.B.OUT1_LS respectively it is working correctly. If I make off CR4...
