The LT8390IFE#PBF is a versatile synchronous 4-switch buck-boost DC/DC controller manufactured by Analog Devices. This controller is designed to regulate output voltage and input or output current from an input voltage that can be above, below, or equal to the output voltage. It features a wide input voltage range of 4V to 60V and supports an output voltage capability from 0V to 60V.
The controller utilizes a proprietary peak-buck/peak-boost current mode control scheme, allowing for adjustable and synchronizable fixed frequency operation between 150kHz and 650kHz. It also offers internal spread spectrum frequency modulation for reduced EMI. Key electrical specifications include a maximum duty cycle of 95%, ±1.5% output voltage accuracy, and ±3% input or output current accuracy with monitor.
Designed for efficiency, the LT8390IFE#PBF achieves up to 98% efficiency. It is available in a 28-lead TSSOP package with an exposed pad, suitable for surface mount applications. The operating temperature range is -40°C to 125°C (TJ). This controller is ideal for various applications including automotive, industrial, telecom, and battery-powered systems requiring robust voltage regulation and current control.
Additional features include current limit, frequency control, and soft start capabilities. The synchronous rectification ensures high efficiency, and the clock sync feature allows for external synchronization. The device is designed for seamless transitions between operation regions, making it suitable for demanding power management tasks.
