The LTC1628CG-SYNC from LT is a high-performance, dual, 2-phase synchronous step-down switching regulator controller. It drives N-channel synchronous power MOSFET stages and 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 from 3.5V to 36V and ±1% output voltage accuracy. The controller supports very low dropout operation with a 99% duty cycle. It also features adjustable soft-start current ramping, foldback output current limiting, and latched short-circuit shutdown with an option to defeat it. Output overvoltage protection is also included.
The device is available in a small 28-lead SSOP package. It offers selectable constant frequency or Burst Mode operation, making it suitable for various power management applications.
Applications include notebook and palmtop computers, PDAs, telecom systems, battery-operated digital devices, and DC power distribution systems.
