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
