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
