                                                                                                    LTC®3607 is a 15V dual 600mA monolithic synchronous step-down regulator which has only 55µA quiescent current. Intended for a variety of applications, including dual lithium-ion battery products, it operates from a wide 4.5V to 15V input voltage range. It features a constant 2.25MHz switching frequency, enabling the use of tiny, low cost capacitors and inductors 1mm or less in height. The internal synchronous power switches provide high efficiency without the need for external Schottky diodes. A user selectable mode input is provided to allow the user to trade off ripple noise for light load efficiency; Burst mode operation provides the highest efficiency at light loads, while pulse-skipping mode provides the lowest ripple noise. To further the maximize battery run time, the P-channel MOSFETs are turned on continuously in dropout (100% duty cycle). Typical applications are dual lithium-ion battery supplies, automotive applications, servers.
