LT3506EDHD Datasheet PDF - Linear Technology

●DESCRIPTION

●The LT® 3506 is a dual current mode PWM step-down DC/DC converter with internal 2A power switches. Both convert ers are synchronized to a single oscillator and run with opposite phases, reducing input ripple current. The output voltages are set with external resistor dividers, and each regulator has independent shutdown and soft-start circuits.
