LTC3415EUHF#PBF

LTC3415 is a high efficiency, monolithic synchronous buck regulator using a phase lockable constant frequency, current mode architecture. PolyPhase® operation allows multiple devices to run out of phase while using minimal input and output capacitance. Burst Mode operation provides high efficiency at low load currents. 100% duty cycle provides low dropout operation that extends operating time in battery-operated systems. The PHMODE pin allows user control of the phase of the outgoing clock signal. The current sense comparator is factory trimmed for accurate output current sharing. Burst Mode operation is inhibited during synchronization or when the MODE pin is pulled low to reduce noise and RF interference. It is used in application such as point of load power supply, portable instruments, distributed power systems, battery-powered equipment etc.
