LV5769V-MPB-E

PMIC - Voltage Regulators - DC DC Switching Controllers

LV5769V-MPB-E is a high performance, single channel synchronous DC/DC buck-boost converter, designed for a wide range of automotive electronics. The LV5769V-MPB-E is a single-port device, meaning it can provide an input voltage and output voltage that are different from each other, providing greater voltage regulation than a traditional standard switching regulator. This DC/DC controller is part of the LV5769V-MPB-E family of automotive controllers from Panasonic, which provides a wide range of DC/DC solutions for a variety of automotive applications.

The LV5769V-MPB-E device supports a buck-boost architecture with a wide input voltage range from 2.6V to 38V and a wide output voltage range of 0.8V-38V. The device includes two operating modes: continuous and burst. In continuous mode, the device delivers a steady, uninterrupted output power. In burst mode, the device switches the output voltage periodically to reduce the power consumed when the system is idle. The LV5769V-MPB-E is equipped with a high efficiency PWM controller and synchronous rectification to ensure low power consumption and to allow for a smaller form factor.

The LV5769V-MPB-E is an automotive grade device, rated for an operating temperature range of -40?C to +85?C, allowing use in a variety of applications. The device is also RoHS compliant and is certified for automotive applications with the ISO/TS 16949 certification, ensuring superior performance and quality.

Application Fields

The LV5769V-MPB-E is ideal for automotive applications where high efficiency, complete protection, robustness, and ease of use are required. Applications include:

• Automotive Battery Management Systems
• Automotive Seat Heater Controllers
• Passenger Comfort Systems
• Lighting System Controllers
• Head Unit Power Supplies
• Rear Seat Entertainment Systems
• Telematics Applications

Working Principle

The LV5769V-MPB-E uses a proprietary adaptive control architecture to ensure a smooth, continuous current flow and minimal input/output voltage ripple. As input voltage or load current varies, the patented adaptive control adjusts switching frequency, inductor current ripple, and switching parameters dynamically to maintain a stable output voltage. This ensures excellent noise immunity and high efficiency in a wide range of applications.

The device is also equipped with a variety of protection functions, including undervoltage lock out (UVLO), overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown (TSD). In addition, the device has built-in short circuit, reverse polarity, and ESD protection to ensure optimal performance, reliability, and safety.
