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.
The operating frequency is externally programmable up to 4MHz, allowing the use of small surface mount inductors. For switching-noise-sensitive applications, the LTC3617 can be synchronized to an external clock up to 4MHz.
Forced continuous mode operation in the LTC3617 reduces noise and RF interference. Adjustable external compensation allows the transient response to be optimized over a wide range of loads and output capacitors.
The internal synchronous switch increases efficiency and eliminates the need for an external catch diode, minimizing external component count and board space. The LTC3617 is offered in a leadless 24-pin 3mm × 5mm thermally enhanced QFN package.
