LTC3828EUH#TRPBF - Dual, 2-Phase Synchronous Step-Down Switching Regulator

The LTC3828EUH#TRPBF is a high-performance, dual, 2-phase synchronous step-down switching regulator manufactured by Linear Technology. It is designed to efficiently convert a wide input voltage range into two lower, regulated outputs with enhanced power density and fast transient response, making it an ideal choice for a variety of applications, including distributed power systems, networking, and telecommunications equipment.

This advanced regulator features a constant frequency, current mode architecture that provides excellent line and load regulation, as well as a strong ability to reject input transients. The LTC3828EUH#TRPBF operates from an input voltage range of 4V to 36V, making it versatile for use in systems with varying supply voltages. Each of the two channels can produce an output voltage as low as 0.6V, which is crucial for powering modern low-voltage digital ICs.

The device incorporates internal switches with RDS(ON) of only 40mΩ and 25mΩ for the top and bottom switches, respectively. This low on-resistance reduces power loss and improves efficiency. The LTC3828EUH#TRPBF also features selectable Burst Mode® operation for improved efficiency at light loads, and a powerful 1.1Ω onboard gate drivers to drive large external MOSFETs for higher current applications.

Additional features of the LTC3828EUH#TRPBF include a programmable fixed frequency from 250kHz to 750kHz, which can be synchronized to an external clock for noise-sensitive applications. It also offers tracking and soft-start capabilities to ensure smooth power-up sequences for sensitive electronic loads. The device provides comprehensive protection features such as overvoltage, undervoltage, overcurrent, and overtemperature protection to safeguard the system under abnormal conditions.

The LTC3828EUH#TRPBF comes in a compact 32-lead (5mm x 5mm) QFN package, which is suitable for space-constrained applications. Its thermally efficient package, combined with its robust design, makes it a reliable choice for high-performance power regulation requirements.

With its advanced features and flexibility, the LTC3828EUH#TRPBF is a powerful solution for designers looking to create efficient, reliable, and compact power delivery systems.
