Resolved! VIPer22A Isolated DC-DC Converter
Hi,When I was trying for DC-DC converter design, I have found this VIPer22A Isolated DC-DC converter design. I am having two queries here,1) Is still this technology in use?2) Can I get the details about the transformer which used here?Is there any n...
STSPIN820 SDBY/RESET pin pulse and time duration details need
I have come across this part for my product for alternate part. we are using reset function as separate pin, and we generate 8.3ms of low pulse for reset function to the motor driver. On your datasheet STSPIN820 IC they general given an active low to...
Resolved! PowerSTEP01 VDDIO Connection
Hi,We are using the chip PowerSTEP01 in our design. In the datasheet, it is mentioned in the application diagram that the VDDIO pin can be powered from the VREG pin. However, the X-NUCLEO IHM03A1 evaluation board design shows that it is powered exter...
STP45N65M5 damaged
Hello. I am using your STP45N FETs in our power supply design for an audio amplifier and we are getting field returns with the STP45N65M5 part damaged. It appears that the gate and source have been shorted but I am not 100% sure. Do you have any insi...
Resolved! L5970AD DCDC schematic doubt
Hello,I am investigating in using L5970AD DCDC converter for a 12VDC to 3V3 need.It was advised to me by the ST DCDC online simulator.It's a 20 year old circuit but it it matches the budget, the additional BOM and the efficiency so I am interested.Bu...
Attempting to use an LDL1117S12R_SOT223 as a current regulator
I'm attempting to use an LDL1117S12R_SOT223 as a current regulator as is shown in application notes for an LM1117 and many similar regulators but it is not working. I have tried it with and without a 4.7uF capacitor across the current setting resist...
unknown fault using STEVAL-L99615C
Hello,I have some questions regarding programming the development kit. We have configured a BMS IC and MCU using a 3-cell setup based on the development kit circuit. Our circuit replicates the schematic and pin configuration of the L99615, connecting...
SPV1050 MPPT Resistor Setting
If you look at the SPV1050 constraints item in 6.4 MPPT Setting in the SPV1050 Datasheet, it is clearly stated that Vmpp(max) should not be applied over 2.1V.However, looking at an4397 (Application Note), even if Vin (Range: 2.6V ~ 9V) is more than 5...
