www.DataSheet4U.com LT3505 1.2A, Step-Down Switching Regulator in 3mm × 3mm DFN DESCRIPTION The LT®3505 is a current mode PWM step-down DC/DC converter with an internal 1.4A power switch. The wide operating input range of 3.6V to 36V (40V maximum) makes the LT3505 ideal for regulating power from a wide variety of sources, including unregulated wall transformers, 24V industrial supplies and automotive batteries. The oscillator can be programmed for high frequency operation allowing the use of tiny, low cost external components or it can be programmed for lower frequency operation to maximize efficiency. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up.
