LV5769V/VZ
Bi-CMOS LSI
1-channel Step-down Switching
Regulator
Overview
The LV5769V/VZ 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
