The LTC3718 is a 1.5V input voltage, synchronous buck/boost controller, for DDR/QDR memory termination. It features low input voltage, fast transient response, high efficiency, true current mode control and more.
The LTC3718 is a high‑current, high‑efficiency synchronous switching regulator controller designed for DDR and QDR memory termination. It operates from a low input voltage as low as 1.5 V and provides a regulated output that tracks ½ Vin or an external reference.
The device uses standard 5 V logic‑level N‑channel MOSFETs, eliminating the need for a sense resistor, and includes features such as programmable soft‑start, output over‑voltage protection, and optional short‑circuit shutdown timer. It is supplied in a 24‑lead SSOP package and is suitable for bus termination, server power, and distributed power systems.
