LTC1628 - DUAL 2-PHASE STEP DOWNManufacturer: Linear Technology
Categories: DC DC Switching Controllers
Quality Control: Learn More
The Linear Technology LTC1628CUH-PBF is a dual 2-phase synchronous buck controller designed for high-efficiency step-down power conversion. This device utilizes current mode control with a wide 3.5V to 30V input voltage range and supports output configurations for positive voltage rails. Featuring a flexible switching frequency selectable from 140kHz to 310kHz, with a nominal 220kHz, it offers two independent output phases for enhanced power delivery and reduced input/output ripple. Control features include current limit, dead time control, enable, frequency control, power good indication, and soft start for robust operation. The LTC1628CUH-PBF is housed in a 32-QFN (5x5) exposed pad package, suitable for surface mount applications. This component finds utility in various demanding industries including telecommunications, industrial automation, and data processing systems where efficient and reliable power management is critical.
