LTC3415 Datasheet 7a Polyphase Synchronous Step-down Regulator

Manufacturer: Linear Technology (now Analog Devices)

General Description

www.DataSheet4U.com High Efficiency: Up to 96% 7A Output Current at VIN = 3V Adjustable Frequency: 1.5MHz Nominal PolyPhase Operation (Up to 12 Phases) Spread Spectrum Frequency Modulation Output Tracking and Margining ±1% Reference Accuracy 2.5V to 5.5V VIN Range Phase Lockable from 0.75MHz to 2.25MHz Selectable Burst Mode® Operation Low Dropout Operation: 100% Duty Cycle Low Quiescent Current: 450μA Current Mode Operation for Excellent Line and Load Transient Response Shutdown Mode Draws Only 0.2μA Supply Current Available in 38-Pin (5mm × 7mm) QFN Package The LTC®3415 is a high efficiency, monolithic synchronous buck regulator using a phase lockable constant frequency, current mode architecture.

PolyPhase® operation allows multiple LTC3415s to run out of phase while using minimal input and output capacitance.

The operating supply range is from 5.5V down to 2.5V, making it suitable for single Lithium-Ion battery as well as point of load power supply applications.
