The LTC3617IUDD#PBF from Analog Devices is a high-efficiency, monolithic synchronous buck regulator. It features a current mode, constant frequency architecture and is optimized for DDR termination applications, supporting DDR, DDR2, and DDR3 standards.
This regulator operates from an input voltage range of 2.25V to 5.5V and can source and sink up to 6A of load current. It provides a regulated output voltage equal to 0.5 • VDDQIN, with an output voltage accuracy of ±10mV. The switching frequency is externally programmable up to 4MHz, allowing for the use of small surface mount inductors. For noise-sensitive applications, it can be synchronized to an external clock.
The LTC3617IUDD#PBF includes an internal amplifier for a VTTR output voltage and an integrated synchronous switch, which increases efficiency and eliminates the need for an external catch diode. It is supplied in a thermally enhanced 24-pin 3mm × 5mm QFN package, suitable for surface mounting.
Key features include ±6A output current, adjustable switching frequency up to 4MHz, and an integrated buffer for VTTR = VDDQIN • 0.5. The operating temperature range is -40°C to 125°C.
