LT3480 is a high efficiency 2A buck regulator that directly accepts wide range input and produces a well-regulated output. The device can be used in automotive and industrial applications.
This document introduces the LT3480, a new monolithic step-down regulator capable of accepting inputs up to 38V (with 60V transient tolerance) while delivering regulated outputs. It features an integrated power switch, constant frequency current-mode architecture, and low quiescent current suitable for battery-powered applications.
The regulator accepts an input from up to 38V, with a capability to handle 60V transients.
The device provides a regulated output at up to 2A across its load range.
The frequency is set between 250kHz and 2.4MHz by using a resistor tied from the RT pin to ground.
