The LT3503EDCB#TRPBF from Analog Devices is a current mode PWM step-down DC/DC converter featuring an internal 1.45A power switch. Its wide operating input range of 3.6V to 20V makes it suitable for various power regulation tasks.
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 electrical specifications include an adjustable output voltage down to 780mV and a maximum output current of 1A. It also features a low quiescent current of 1.9mA when not switching and less than 2µA in shutdown mode.
The device is designed for applications such as automotive battery regulation, industrial control supplies, and battery-powered equipment. It comes in a thermally enhanced, 2mm x 3mm 6-pin DFN low-profile package, suitable for surface mounting.
Additional features include cycle-by-cycle current limit for short-circuit protection and soft-start to eliminate input current surge during start-up. The internal compensation simplifies design, and the low VCESAT switch (400mV at 1A) contributes to efficiency.
