DESCRIPTION\nThe LT®3508 is a dual current mode PWM step-down DC/DC converter with internal power switches capable of generating two 1.4A outputs. The wide input voltage range of 3.7V to 36V makes the LT3508 suitable for regulating power from a wide variety of sources, including automotive batteries, 24V industrial supplies and unregulated wall adapters. Both converters are synchronized to a single oscillator programmable up to 2.5MHz and run with opposite phases, reducing input ripple current.FEATURES\n■ Wide Input Voltage Range: 3.7V to 36V\n■ Two 1.4A Output Switching Regulators with Internal Power Switches\n■ Adjustable 250kHz to 2.5MHz Switching Frequency\n■ Synchronizable over the Full Frequency Range\n■ Anti-Phase Switching Reduces Ripple\n■ Uses Small Inductors and Ceramic Capacitors\n■ Accurate Programmable Undervoltage Lockout\n■ Independent Tracking, Soft-Start and Power Good Circuits Ease Supply Sequencing\n■ Output Adjustable Down to 800mV\n■ Small 4mm × 4mm 24-Pin QFN or 16-Pin Thermally Enhanced TSSOP Surface Mount PackagesAPPLICATIONS\n■ Automotive\n■ DSP Power Supplies\n■ Wall Transformer Regulation\n■ DSL and Cable Modems\n■ PCI Express
