We are designing PFC converter using L6562A controller for 340Vac-440Vac to 665Vdc with 250W as output power.We are facing problems of very low Power factor at lighter loads.What might be the possible reasons for this and how can we tackel this? Rega...
I don't know the internal structure of the TS3330AMR IC.Is there a functional block diagram of the IC's internal structure?
I developed a multi-port charger with multiple STUSB4710A and companion ST1S14PHR with the recommended bill of materials. The evaluation kit worked fine however my board does not work consistently. I read back the status register and detecting underv...
Hi,L7987L IC is used for generating -15V from 24V supply. it was working OK up to 12V, upon further increasing Supply Voltage we found arc at the soft start pin.
Register 6Fh, D[1] SPI_HSoff_highLow ohmic path switch off disable bit for HS pre-driver stage A and B0 / R/W (default) (‘1’ = low ohmic path enabled)When D[1] =0, Low ohmic path between HS driver GHy_x and SHy_x is connected or disconnected?When H-...
Per example code of L9369, to set SPI_set_PWM, one read-write operation for 6Ah is used and to set SPI_PWM_A, another read-write operation for 6Ah is used. My question: Can two separate read-write operations be merged into only one? Thanks!
EN_EL pin (#47) is originally EN function and to set it as RST function, need to set D[4] of reg8Ah. My question: When to set D[4] to 1 to enable RST function? should it do after setting watchdog ? Thanks! RST Remapping on EN_EL the function of I...
Hi.I am using the L6599AD without PFC.Previously, the DIS pin was connected to the DELAY pin and used as a SHUTDOWN.However, the frequent peak current caused SHUTDOWN.So I connected the DIS pin to GROUND and made it work in HICCUP MODE.However, the ...
Hello,I have developed a custom board using the STPM33 to measure power consumption. The schematic is identical to the evaluation board.I can communicate with the STPM33 via SPI and have verified that the data I write is correctly stored in the devic...
Hello Anyone did ever you use the MC34063ACD-TR for to power on a "MCU" at 3.3V? From datasheet it seems it needs change R1 and R2 for to obtain the goal but the figure 15 shows until 5V so..I ask you if i can use it for my application. My applicatio...
