LTC3726EGN#PBF - Dual 1-Phase Synchronous Step-Down Controller

The LTC3726EGN#PBF is a high-performance dual 1-phase synchronous step-down switching regulator controller from Linear Technology that drives all N-channel power MOSFET stages. Its advanced design is targeted for applications such as point-of-load power supply systems, distributed power systems, and other systems requiring a compact, high efficiency power management solution.

Key Features:

• Wide Input Voltage Range: The device can operate from an input voltage range of 4V to 36V, making it suitable for a wide variety of supply sources, from standard 5V, 12V, and 24V rails to unregulated or fluctuating supplies.
• Dual Outputs: The LTC3726EGN#PBF can simultaneously regulate two outputs that can be set by external resistors. Each channel is capable of driving a synchronous step-down circuit, providing flexibility for various output voltage requirements.
• High Efficiency: With its synchronous operation, where the top and bottom MOSFETs are turned on and off complementarily, the LTC3726EGN#PBF achieves high efficiency, which is crucial for thermal management and energy savings.
• Phase-Lockable Fixed Frequency: The switching frequency is selectable from 250kHz to 750kHz and can be synchronized to an external clock, which helps minimize electromagnetic interference (EMI) and allows for use in noise-sensitive applications.
• OPTI-LOOP Compensation: The LTC3726EGN#PBF incorporates 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 high level of safety and reliability.
