Vicor Corporation Voltage Regulators - DC DC Switching Regulators PI3749-00-LGIZ

The PI3749-00-LGIZ is a high-efficiency DC-DC ZVS Buck-Boost regulator designed for a wide input voltage range of 16V to 34V and capable of delivering up to 240W of continuous output power. This System-in-Package (SiP) integrates the controller, power switches, and necessary support components, facilitating a compact design. The Zero-Voltage Switching (ZVS) topology enhances performance by minimizing switching losses and maximizing efficiency, achieving up to 98.5% efficiency at a switching frequency of 800kHz. The device supports fast transient response and is capable of parallel operation with single wire current sharing. It includes features such as input over/undervoltage lockout, output overvoltage protection, and overtemperature protection, ensuring robust operation in various applications. The operating temperature range is from -40°C to 115°C, making it suitable for demanding environments. The package dimensions are 10mm x 14mm x 2.56mm, and it requires external components like an inductor and capacitors for complete functionality. This regulator is ideal for applications in computing, communications, and industrial settings where variable output voltage regulation is needed.
