The LV5069JA-ZH is a high-efficiency, step-down switching regulator controller. It is specifically designed for automotive applications and offers improved performance over similar competing devices. The device has a wide voltage input range, up to 50V, and is capable of delivering output currents up to 2A. A variety of protection functions are available, including overvoltage, current limiting, and over temperature protection, making the LV5069JA-ZH suitable for automotive power supplies, DC-DC converters, LED drivers and power supplies.

The LV5069JA-ZH is a 3-pin non-isolated switching regulator controller with a built-in low-voltage detector and startup circuits. The device operates in a synchronous buck topology with a fixed output voltage, and provides high efficiency up to 96%. The device incorporates a multiplier and shift register control circuit that consists of a voltage control pin and a voltage monitoring pin, allowing the output voltage to be accurately programmed over a wide range. The on-time and off-time of the converter are automatically adjusted to compensate for the ripple in output voltage, allowing the system to maintain a constant output voltage.

The LV5069JA-ZH utilizes a unique high-tolerance current-mode control. This provides fast line and load transient response and also reduces part count as it eliminates the need for large filter components. The device provides a built-in soft start function that allows the control circuit to gradually reach the intended initial operating condition, resulting in reduced inrush current at startup. The device also provides a wide range of protection features, including overvoltage protection, current limiting, over temperature protection, and thermal shutdown.
