Product Summary

The LT3493EDCB#TRPBF is a Step-Down Switching Regulator. The LT3493EDCB#TRPBF is a current mode PWM step-down DC/DC converter with an internal 1.75A power switch. The wide operating input range of 3.6V to 36V (40V maximum) makes the LT3493EDCB#TRPBF ideal for regulating power from a wide variety of sources, including unregulated wall transformers, 24V industrial supplies and automotive batteries. Its high operating frequency allows the use of tiny, low cost inductors and ceramic capacitors, resulting in low, predictable output ripple. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. The low current (<2μA) shutdown mode provides output disconnect, enabling easy power management in battery-powered systems. The applications of the LT3493EDCB#TRPBF include Automotive Battery Regulation, Industrial Control Supplies, Wall Transformer Regulation, Distributed Supply Regulation and Battery-Powered Equipment.
