EVLVIPGAN50PD Modification for Standalone 12V Power Supply
Hi Sir, I would like to explore a specific use case that deviates from the standard design. My goal is to modify the EVLVIPGAN50PD to achieve a fixed 12V output, bypassing the USB PD negotiation functionality entirely. My intention is to utilize only...
Mastergan5 - Switching losses
Hi,I'm interested in the Mastergan5 IC.To evaluate it for our use case in a Class-D amplifier we need information about switching losses.These are commonly provided by suppliers of half bridge ICs by providing the Eon and Eoff values over switching v...
STM6600 Implementation Queries
Hi,We are implementing STM6600 push button controller for our design and we have below queries. Is there any pull up connected to PS hold pin, can I connect this directly to 3.3V logic MCU.For variant STM6600DU25DM6F, tON blank is 11.2s, Do we need t...
STPM32 triggers interrupt for non masked bits.
Hello,I use a STPM32 on a battery charge system. The STPM32 is associated with an ESP32 module.The driver used is from ST (V1.0, 17 may 2016).I want to detect some defaults with interrupt, and I configure the interrupt mask only for current and volta...
L9524C Control Input Signal Max. Duty Cycle Value
I have already using L9524C IC for glow plug controller. I have to must to learn that what is the maximum duty cycle value of Control Input (CI) PWM signal?And if I have apply continuous HIGH signal to Control Input pin, how L9524C works? Freq. is 40...
Clarification on STUSB4710QTR Configuration for 5V/5A Power Source
I just need some clarification regarding the STUSB4710QTR.I'm designing a USB-C power source where a USB 2.0 hub will supply 5 V/5 A to a USB device. The connected device is a USB cellular modem, which typically draws a continuous 5 V/3 A, but requir...
STSPIN948 and stepper motor
Hi,does anyone in the world have used a STSPIN948 with a stepper motor?I'm having many problems, also because of lack of documentation and examples.I need to control a NEMA 23 motor, but if it turns slowly it works, over 2 turn per second it hangs.I ...
L4985A_PFC issue
HiI am using L4985A for my 110W PFC design. During testing boost inductor current is getting distorted when i increase the load. And also, audible noise from the boost inductor. Here I attached the waveform. I used eDesign suite for designing and sim...
STC3115 - do we really need to use the RAM
HiI am looking into STC3115 for a device, powered by a LiPo battery. The battery is not removable, main CPU turns off during low-power states.Looking at the AN4324 system integration manual, it describes the procedure to use the embedded RAM to save ...
Resolved! ST1S12G18R Output Voltage Issue - Feedback Not Functioning Properly
Hello,I'm encountering an issue with the ST1S12G18R DC/DC regulator. I've attached the reference schematic from the datasheet and my PCB layout, created in Altium. As you can see, my design matches exactly with the reference schematic provided by ST....
