The LTC3728LXCUH#TRPBF is a high-performance, dual synchronous step-down switching regulator controller from Linear Technology, a leader in the design and manufacture of high-performance analog integrated circuits. This product is designed to drive power MOSFETs and is ideal for CPU power supplies, distributed power systems, and other applications requiring a compact, high-efficiency power solution.

Key Features:

• Wide Input Voltage Range: Operates from a 4V to 36V input voltage range, making it suitable for a variety of supply voltages.
• Dual Output Channels: Features two output channels, each capable of driving a synchronous rectifier power stage, which allows for efficient power conversion with reduced heat dissipation.
• Adjustable Switching Frequency: Users can set the switching frequency from 250kHz to 750kHz or can synchronize it to an external clock.
• Phase-Lockable Frequency: 250kHz to 550kHz with the ability to synchronize to an external clock, ensuring noise-sensitive applications can avoid critical frequency bands.
• OPTI-LOOP® Compensation: Minimizes the output voltage overshoot and allows for a wide range of output capacitors and inductors.
• Current Mode Operation: Provides excellent line and load transient response.
• Power Good Output Voltage Monitor: Signals when the output is within 7.5% of the regulated voltage, providing system-level monitoring and control.

Applications:

• Multi-phase CPU power supplies
• Distributed Power Systems
• Telecommunications infrastructure
• Datacom and Telecom Systems
• High-density power modules
