CXSU63283 series products are a PFM controlled boost DC-DC converter with low power consumption, high efficiency, low ripple and high operating frequency. The built-in ULVO circuit of the chip can detect the input voltage, adjust the filtering time of UVLO through the external capacitor, and realize the undervoltage protection function of the chip through the external capacitor and the built-in UVLO. After the undervoltage protection, the undervoltage protection can only be canceled by repowering on (higher than the UVLO voltage). The chip has built-in a discharge lamp. After UVLO, the chip realizes fast discharge through built-in a discharge lamp. CXSU63283 series products only need 6 external units to complete low input battery voltage input.
