Unexpected High Inrush Current in DC-DC Converter Startup
Hello everyone,I’m currently working on a DC-DC buck converter design using the [insert IC name, e.g., ST1PS03] for a low-power embedded system. During startup, I’m noticing a very high inrush current that causes voltage dips on the input rail.Here a...
Problem with in rush current to the DC Link Capacitor
In the DC Link Capacitor i am facing a problem like i am getting 260Arms as the inrush current for my motor controller. Although my overall operating current is 160Arms maximum. Suggest me some methods to reduce this consition.
L9780 Supporting Firmware
Hello,Does anyone have any firmware for interfacing with the L9780 wideband controller. I am planning on using a LSU 4.9 but any sensor configuration would be useful.Any information is appreciated. Thanks,
Requesting Spice Model for L9338
Hello I’m currently working on a design that uses the L9338 Quad Low-Side Driver and would like to perform circuit simulations in LT spice (or any compatible simulator). Could you please provide the SPICE model for the L9338?If it’s not available pub...
Resolved! STUSB4500 Variable Voltage
Hello, Is there a way to set up the Sink PDO to take in a variable voltage? I would like to set up PDO2 5-20V 3AmpsPDO3 5-20V 5Amps My plan is to use the Power Ok GPIOs to determine how much current I have and do some down stream current limiting. ...
SRK1000 usability test remarks
Last week, I have been testing SRK1000A in EVLSRK1000A-PF, in an application with 250 kHz fixed frequency flyback PWM with primary side control.1. I struggled around the gate no longer driven in CCM-mode, and even in DCM upon more than moderate load....
Resolved! VN9E30F: SPI Error & Fail Safe mode isnot getting clear.
Hello,I am trying to send first command from the MCU (s32k312 -NXP).I am able to send but I am getting SPI response likeAnd afterwards, no matter which SPI commands send, it always sends same response from the chip i.e. 0x610000As per the Datasheet, ...
L99LDLH32 modify Responder ID issue
Hi everyone,Good day!I'm currently working on modifying the Responder ID using CAN FD communication.I initially had a firmware running on an MCU that was capable of modifying the Responder ID. My goal now is to analyze the CAN FD communication from t...
L6982CDR application problem.
Hi,We're encountering an issue with the L6982CDR buck converter in our application. Here's the detailed scenario: Configuation: We're using it to convert a 24V input to a 5V output to power the board. Load: The 5V output supplies a load current of ap...
Resolved! STW3N170 - DC SOA
Hi ST,I am using the STW3N170 in a linear application (constant current source) where the voltage can be 1500V and current as high as 16mA - total 24W.Can you please share the DC Curve of the SOA, please include in the graph the Thermal Instability d...
