ALTAIR04-900 switching frequency in burst mode
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...
Resolved! SPV1040 - using LX to generate a boost supply
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...
Wlc38 Digital Ping Power Consumption
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...
STWLC89 application related
Hi,Since we haven’t received the datasheet yet, we’d like to confirm the following information:If the receiver side (RX) uses the STWLC89 15 W solution, what is the corresponding 15 W transmitter (TX) model?Which Qi standards are supported by STWLC89...
Resolved! About High Side Driver Selection
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...
STPMIC1D Boost bypass
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
Resolved! Search for datasheet
I can't read référence; I am asking if this component is a zener Diode? And I'm looking for any équivalence
ACS, ACST negative voltage schematics ?
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...
Resolved! Encrypted Spice model for altair04-900
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, ...
Viper12, AC-DC non isolated Buck converter 5V 60mA
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,...
