STCH03 does not seem to detect an over voltage state
Hi,I'm testing a simple flyback converter using the STCH03L. All seems as expected, however I can not seem to get the IC to detect an overvoltage condition. To conduct the test I am simply shorting out the optocoupler. When I look at the ZCD pin the ...
Resolved! Discharging a thin film battery - EFL700A39
Hello,I'm trying to discharge the solid state thin film lithium battery EFL700A39, with a discharge current of 0.7 mA, in the aim of reaching a state of charge of approximately 20%. Actually, the problem is the significant difference of voltages whe...
SPV1050 boost start-up at Vstore=0 with low-impedance source
The datasheet (https://www.st.com/resource/en/datasheet/spv1050.pdf) mentions that the STORE voltage during initial start is charged through a charge pump, when in boost configuration.However, when I set my load to 0 V and input to 2 V, it sure seems...
SPV1050 current limiting relationship to Veoc
I have an SPV1050 configured as follows:R4 = 6.2MR5 = 1MR6 = 3.9MVeoc = 3.5VVuvp = 2.78VThe device is configured for boost mode with MPPT set to 75% and Vin = 2V. The device works as expected, except that it will only draw the full specified 70mA cu...
