LT8330IDDB#TRMPBF

LT8330IDDB#TRMPBF is a synchronous device for high quality DC/DC conversion. The device can operate as a step-down, step-up, or voltage inverting converter. It is designed to operate from 3.5V to 28V input, and is capable of delivering up to 5A of continuous output current. The device has a built in high performance power MOSFET and P-channel MOSFET for better performance and efficiency.

Application Field

The LT8330IDDB#TRMPBF has a wide variety of applications and is suitable for portable, battery-powered applications such as cell phones, digital cameras, portable audio players, GPS receivers, tablets, and other portable devices requiring high efficiency and low quiescent current. It can also be used in industrial, automotive, and telecom systems.

Working Principle

The LT8330IDDB#TRMPBF is based on synchronous, high efficiency buck topology. It employs a high-frequency current mode of operation for excellent line and load regulation. The device takes an input voltage, and regulates it to a regulated output voltage at the desired output current. The output voltage is set using an external voltage divider.

The device utilizes a proprietary architecture which combines high switching frequency (up to 1 MHz) with very low quiescent current to improve efficiency while minimizing heat dissipation. The device also provides a sensing pin to detect overcurrent conditions and protect against overload. The device can also be configured for true electrically-isolated operation.

The LT8330IDDB#TRMPBF benefits from advanced Fast Transient turn-on and enhanced load transient performance, allowing for greater flexibility in the design of the power supply system. All the above features come together to improve overall system performance and reliability.
