Regulator
Overview
The LV5768V is a 1-channel step-down switching regulator.
Functions
• 1 channel step-down switching regulator controller.
• Frequency decrease function at pendent.
• Load-independent soft start circuit.
• ON/OFF function.
• Built-in pulse-by-pulse OCP circuit. It is detected by using ON resistance of an external MOS.
• Synchronous rectification
• Current mode control

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high
voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
