Product Overview

The LT3503EDCB#PBF is a current-mode PWM step-down DC-to-DC Converter with an internal 1.45A power switch. The wide operating input range of 3.6 to 20V makes the LT3503 ideal for regulating power from a wide variety of sources. Its high operating frequency allows the use of tiny, 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.
