The LTC3728EG is a high-performance dual synchronous step-down switching regulator controller designed by Linear Technology. It is tailored to deliver precise voltage regulation and high efficiency for advanced microprocessors, FPGAs, and other power-sensitive applications.

Key Features

• Versatile Power Supply: The LTC3728EG operates from a 4V to 36V input voltage range, making it suitable for a variety of supply sources, including intermediate bus voltages in telecom and industrial applications.
• Dual Outputs: It features two independent output channels, each capable of driving a synchronous rectifier MOSFET stage. This allows for two separate regulated voltages or a higher current output through combined channels in a 4-phase operation.
• High Efficiency: With its synchronous operation and low dropout voltage, the LTC3728EG achieves high efficiency, which is critical for reducing heat and improving system reliability.
• Phase-Lockable Fixed Frequency: The switching frequency is selectable from 250kHz to 750kHz and can be synchronized to an external clock for noise-sensitive applications.
• OPTI-LOOP Compensation: The LTC3728EG incorporates Linear Technology's proprietary OPTI-LOOP compensation, which allows the transient response to be optimized over a wide range of output capacitance and ESR values.
• Robust Protection Features: It includes overvoltage protection, undervoltage lockout, and a foldback current limit, providing a safeguard for your system under abnormal conditions.
