PRODUCTION DATA
Both converters have implemented soft-start functions. When each converter is enabled, the implemented switch current limit ramps up slowly to its nominal programmed value in typically 1ms. The device includes this function to limit the input current during start-up to avoid high peak input currents, which could interfere with other systems connected to the same battery or supply.
If the application includes the Load Disconnect PMOS switch, a current flows from the input to the output of the boost converter at the moment the PMOS switch becomes conducting.
