Product Overview: LTC3828EUH#PBF

The LTC3828EUH#PBF is a high-performance, dual, 2-phase synchronous step-down DC/DC controller from Linear Technology, designed to drive all N-channel power MOSFET stages. It is well-suited for applications requiring a compact, high-efficiency power delivery solution. With its wide input voltage range from 4V to 36V, it can accommodate a variety of supply voltages, making it a versatile choice for diverse electronic systems.

This controller integrates a powerful 1.1Ω on-chip gate drivers, providing strong driving capability for MOSFETs to ensure efficient power conversion. The LTC3828EUH#PBF operates with a selectable fixed frequency between 250kHz to 750kHz and can also be synchronized to an external clock within the same range, giving designers flexibility to optimize the solution for performance and component size.

The LTC3828EUH#PBF features phase-lockable frequency modulation (PLL) for noise-sensitive applications, ensuring low noise and minimal interference with other system components. Its current mode operation provides excellent line and load transient response, which is critical for maintaining stable output voltages in the face of varying load conditions.

Additional features include a differential output voltage sensing for improved accuracy, and a powerful 1.5% 0.8V reference, which allows for precise control of the output voltage. The device also offers optional output voltage tracking for sequencing multiple power rails in a system. Its overvoltage protection and foldback current limit provide safeguards for the power supply and the load, enhancing system reliability.

The LTC3828EUH#PBF comes in a compact (5mm x 5mm) QFN-32 package, which is ideal for space-constrained applications. It is suitable for a wide range of applications, including telecommunications, networking equipment, industrial systems, and portable devices that require efficient power management solutions.

As part of Linear Technology's commitment to high-quality products, the LTC3828EUH#PBF is designed to meet the stringent requirements of modern electronic systems, delivering efficient power conversion with robust protection features.
