The LTC1628CG-SYNC#TRPBF from Analog Devices is a high-performance, dual step-down switching regulator controller designed to drive N-channel synchronous power MOSFET stages. It utilizes a constant frequency current mode architecture, allowing for a phase-lockable frequency up to 300kHz. This design minimizes power loss and noise by operating the two controller output stages out of phase.
Key electrical specifications include a wide input voltage range of 3.5V to 30V (36V maximum) and ±1% output voltage accuracy. The controller offers very low dropout operation with a 99% duty cycle. It supports adjustable soft-start current ramping, foldback output current limiting, and latched short-circuit shutdown with a defeat option. Output overvoltage protection is also included.
This device is housed in a compact 16-SSOP package, suitable for surface mount applications. It operates within an ambient temperature range of 0°C to 85°C. The controller features include Enable, Frequency Control, Power Good, and Soft Start functions, making it versatile for various power management applications.
Applications include notebook and palmtop computers, telecom systems, battery-operated digital devices, and DC power distribution systems. The out-of-phase controllers reduce required input capacitance and power supply induced noise.
