    LT3506/LT3506A
    Dual Monolithic 1.6A
    Step-Down Switching Regulator
    FEATURES DESCRIPTION n The LTВ®3506 is a dual current mode PWM step-down DC/DC
    converter with internal 2A power switches. Both converters 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.
    Each regulator generates a power-good signal when its
    output is in regulation, easing power supply sequencing
    and interfacing with microcontrollers and DSPs. Wide Input Voltage Range, 3.6V to 25V
    Two 1.6A Output Switching Regulators with Internal
    Power Switches

    Design Note 404
    Hua (Walker) Bai
    Introduction
    Electronic devices are becoming smaller while the power
    requirements are increasing to satisfy ever more functionality. To preserve power and manage heat, switching
    regulators are desirable because of their high efficiency
    compared to linear regulators.
    The LT3506 and the LT3506A are examples of how to
    squeeze power out of a supply without overheating the
    end product. These are dual 1.6A step-down monolithic
    regulators that simplify the lives of system engineers. They
    eliminate the need for external power switches, thereby
    reducing solution size and BOM cost. Their outputs can
    be as low as 0.8V, satisfying the needs of the latest DSPs.
    Integrated dual output channels reduce the part count,
    while anti-phase switching of the two channels maximizes
    efficiency and reduces input current ripple and EMI. Both
