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...
