LV5069JA is Step-down switching regulator controller. The recommended operating range is 4.5V-23V. The operating
current is about 68μA, and low power consumption is achieved.
Features and Functions
•
Typical value of light load mode current is 68μA
•
4.5V to 23V Operating input voltage range
•
The oscillatory frequency can be set by the external pin. The oscillatory frequency is 300kHz - 1MHz.
•
Output voltage adjustable to 1.26V
•
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
•
External capacitor Soft-Start
•
Under voltage lock-out, Thermal shutdown and power good indication
Applications
•
DVD/Blu-rayTM Drivers and HDD
•
LCD Monitors and TVs
•
Point of Load DC/DC Converters
•
Office Supplies

Caution 1) Absolute maximum ratings represent the values 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.
