Overview
LV5068V is 1ch step-down switching regulator. The operation current is about 80μA, and low power consumption is
achieved.
Functions
• 1ch SBD rectification controller IC
• Maximum value of light load mode current is 80μA.
• Built-in OCP circuit with P-by-P method
• When P-by-P is generated continuously, it shifts to the HICCUP operation.
• If connect C-HICCUP to GND pin, then latch-off when over current.
• The oscillatory frequency can be set by the external pin. The oscillatory frequency is 300 kHz to 2.2MHz
• Built-in UVLO, TSD
• Synchronous driving with external signal
