L5973D - 100% Duty Cycle Not Working

Hi,I have an L5973D set up for 28.5V output from 30V ish input for 2A current. The design requires the regulator to go to 100% duty cycle when the input voltage drops. At low currents (up to 1.5A) the device behaves correctly and smoothly transition...

Hello ST At what update rate can dither be applied to the onboard 4 bit DACs of the STLUX385A power management ICs? Is there any internal filtering on the output of the DAC prior to the analog comparator stage? best regards, Craig MacKinnon

Hi, I have a problem with 2 P/N LF33CV : they don't work properly. The output voltage is 7,8V. I have tried 2 LF50CV instead and no problem, the output is 5.0V A problem with that component ?

power mosfet without body diode

Hello we need a power mosfet without body diode for bidirectional applications . Is there a power mosfet like above? as well as is there a mosfet that has substrate Pin available? Sincerely mohammad maghsoodi

How can I configure BQ78350-R1 using STM32 with SMBus communication?

Selecting SPV1040 for energy harvesting from solar cell

Hi,This is John from Qmax Systems, We are designing a product - energy harvesting from solar cell. Our application requires a boost converter to convert 0.5V to 4.2V with an output current of min 100 mA. Do you think LTC3105 will support this applica...

SPV1040 not working as specified in the datasheet

Hello. I am using the SPV1040 solar boost converter within the STEVAL-ISV012V1 development board. The datasheet states that the converter can work with an input voltage as low as 0.3 V. The solar cell I am using is able to provide 0.6 V (Voc) and 100...
