Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
HI! We have from time to time defect High Side Driver. Most of the defects occur after the first few power on cycles. The High Side Driver and the RGND Resistor (120Ohm) gets really hot. The resistance between GND and the Status Pin is then much l...
Hello! I am building a 50-600Vin flyback converter using the altair04-900 to power an LED as a student project. Due to the very light load I expect it to work in Burst mode. Currently I am looking for an adequate transformer. On this regards my quest...
This is to turn on MOSFETs that operate above 5.2V supply of the Boost regulator. I have followed a forward converter guidance roughly in one of the application notes, but I have not used a transformer but placed a high value resistor in the voltage...
Hello, We are looking to use the Wlc38 in Bi-directional mode alternating between RX and TX digital pings. We are wondering how much power consumption the digital ping takes and for what duration so we can calculate power consumption of pinging at va...
Hello everyone,I am finding to drive for 4 cabin lock. For this, VNxxx or VNQxxx series help me. I don't need high current. It is 1 amper per channel(per output. I'm looking for a chip that will not cause any supply problems and will be produced con...
HiIs it possible to bypass the boost by applying a 5V voltage directly to BSTOUT (VLXBST is left unconnected)?Thank in advance for your reply
I can't read référence; I am asking if this component is a zener Diode? And I'm looking for any équivalence
I found the ACS108-6SA that seems to fit my needs. 1) I will control the gate with my stm32G0B1 uC. I really don't understand why I have to connect the 24VAC Neutral to the +3.3VCC of the MCU ! It sounds like dangerous no? i can understand that the...
Hello!I am currently designing a flyback converter with the altair04-900.The .lib file in the spice model folder is encrypted. I cannot open it neither with Altium nor with ltSpice.I would like to know, which simulation software can decrypt it? And, ...
Hello, I'm considering using Viper12 to 3Phase AC/DC non isolated buck converter 5V 60mA Vout. I found some application notes like AN1357. But is it reliable? Or will it cause problems in long-term operation? Has anyone experienced it before? Thanks,...
