LV5725JA
Bi-CMOS LSI
Step-down Switching Regulator
Overview
The LV5725JA is a step-down voltage switching regulator.
Functions
• Wide input dynamic range: 4.5V to 50V.
• Current mode type.
• Built-in pulse-by-pulse OCP circuit: detection is on resistance of an external MOS.
• Over current protection: HICCUP mode.
• Thermal shutdown.
• Load-independent soft start circuit
• ON/OFF pin
• Synchronous operation by external signal.
• Power good pin
• External voltage is usable when output voltage is high.
