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.

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.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
