The LTC3617 is a high efficiency monolithic synchronous buck regulator utilizing a current mode, constant frequency architecture. It operates from an input voltage range of 2.25V to 5.5V and provides a regulated output voltage equal to 0.5 • VDDQIN while sourcing and sinking up to 6A of load current. An internal amplifier provides a VTTR output voltage equal to 0.5 • VDDQIN with an output current capability of ±10mA.
