WLC38 - compatible chargers
Hi,We are developing a product using the WLC38 as RX.It works OK in combination with wbc2tx50 board, and a single Spigen QI charger we found (no overheating, constant power > 10W achievable).However using any other charging pads (either Qi1 15W or Qi...
L99DZ100G Out1 to Out6 remains High by default.
I am working on L99DZ100G IC. I am able to communicate with L99DZ100G correctly. But when I check Out1 to Out6 , I am getting 12V by default. If I make on and off CR4.B.OUT1_HS and CR4.B.OUT1_LS respectively it is working correctly. If I make off CR4...
L9369's problem shooting
Hello. I'm using L9369 IC and have a problem. Stage A is not working. i made control code for Stage A,B. (they are very similar) i used below two command for H-brdige operation. but. current was not flow. here is phenomenon. 1.Low side GL1,...
Poor PF at light loads
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...
Resolved! About the TS33 series
I don't know the internal structure of the TS3330AMR IC.Is there a functional block diagram of the IC's internal structure?
Resolved! STUSB4710A output not stable
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...
l7987l Arcing across soft start pin
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.
[L9369] Reg 6Fh D[1] =0 to set Low ohmic path to be connected or disconnected?
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-...
