The Analog Devices LT3503EDCB#TRPBF is a high-performance, current-mode PWM step-down DC/DC converter. It integrates a 1.45A power switch and operates with a wide input voltage range from 3.6V to 20V, making it suitable for various power sources.
This regulator operates at a fixed frequency of 2.2MHz, allowing for the use of small, low-cost inductors and ceramic capacitors, which contribute to low and predictable output ripple. Key features include cycle-by-cycle current limiting for protection against output shorts and soft-start to eliminate input current surges during startup.
The LT3503EDCB#TRPBF is housed in a thermally enhanced, 2mm x 3mm DFN low-profile package. Its low shutdown current of less than 2µA is beneficial for power management in battery-powered applications. The output voltage is adjustable down to 780mV.
Typical applications include automotive battery regulation, industrial control supplies, wall transformer regulation, distributed supply regulation, and battery-powered equipment.
