LV5068V
LV5068V is Low power consumption and high efficiency Step-down Switching Regulator Controller manufactured by onsemi.
Ordering number : ENA1875
Bi-CMOS IC
Low power consumption and high efficiency Step-down Switching Regulator Controller http://onsemi.
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 k Hz to 2.2MHz
- Built-in UVLO, TSD
- Synchronous driving with external signal
