LTC3708EUH#TRPBF - High Efficiency, Dual N-Channel Synchronous Step-Down Controller

The LTC3708EUH#TRPBF is a state-of-the-art, dual N-channel synchronous step-down switching regulator controller manufactured by Linear Technology, which is now part of Analog Devices. This advanced controller is designed to drive all N-channel power MOSFET stages, which can significantly enhance system efficiency and reduce overall power loss. It is a versatile and powerful solution for complex power supply systems requiring dual outputs or two-phase operation.

This controller is housed in a compact 32-lead (5mm × 5mm) QFN package, making it suitable for space-constrained applications without compromising performance. Its high operating frequency allows the use of small, low-cost inductors and capacitors, resulting in a compact, efficient power supply design.

The LTC3708EUH#TRPBF incorporates Linear Technology's proprietary No RSENSE™ technology, which eliminates the need for a current sense resistor by utilizing the voltage drop across the inductor (DCR) for current sensing. This unique feature simplifies the design and improves efficiency by reducing power loss.

With a wide input voltage range from 4V to 36V, the LTC3708EUH#TRPBF is suitable for a variety of applications, including telecommunications, networking, and industrial systems. The device's output voltage is adjustable down to 0.8V, which allows it to cater to modern low-voltage requirements in digital circuits.

Key features of the LTC3708EUH#TRPBF include phase-lockable fixed frequency from 250kHz to 750kHz, selectable continuous or discontinuous operation, and a powerful 1.1Ω onboard gate drivers. It also provides protection features such as overvoltage protection, undervoltage lockout, and thermal shutdown to ensure the reliability and durability of the end application.

The LTC3708EUH#TRPBF is an ideal solution for designers looking for a high-performance, dual output or two-phase synchronous step-down controller. Its advanced features and compact design make it a perfect choice for creating efficient, reliable, and high-density power supply systems.
