The LTC1628CG#TRPBF from Analog Devices is a high-performance dual step-down switching regulator controller designed to drive N-channel synchronous power MOSFETs. It utilizes a constant frequency current mode architecture, allowing for adjustable frequencies up to 300kHz, though the nominal frequency is specified at 220kHz. The controller operates with a wide input voltage range of 3.5V to 30V and features very low dropout operation with a maximum duty cycle of 99.4%.
Key features include OPTI-LOOP compensation for minimized output capacitance, -1% output voltage accuracy, and dual N-channel MOSFET synchronous drive. The device supports adjustable soft-start current ramping, foldback output current limiting, and latched short-circuit shutdown. The LTC1628CG#TRPBF is available in a 16-SSOP package and is suitable for surface mount applications. It operates within a temperature range of 0°C to 85°C (TA).
This controller is designed for applications requiring efficient power conversion, such as notebook computers, battery chargers, and portable instruments. Its dual-phase operation helps reduce input capacitance requirements and power supply induced noise. The integrated control features like Power Good and Soft Start aid in system design and stability.
