LT3581IDE#TRPBF Description

Short technical summary and product information.

The LT3581IDE#TRPBF is a versatile PWM DC/DC converter from Analog Devices, designed with integrated fault protection for output shorts, input/output overvoltages, and overtemperature conditions. It features a combined 3.3A power switch, capable of operating in Boost, SEPIC, Inverting, or Flyback configurations. The device supports a wide input voltage range from 2.5V to 22V, with a maximum transient rating of 40V.

 

This converter can generate various output voltages, such as 12V at 830mA or -12V at 625mA from a 5V input. Its switching frequency can be set between 200kHz and 2.5MHz, and it can be synchronized to an external clock. The LT3581IDE#TRPBF includes features like frequency foldback and soft-start, along with user-configurable undervoltage lockout.

 

Packaged in a 14-pin DFN (4x3mm) with an exposed pad, this component is suitable for surface mounting. Its applications include local power supplies, vacuum fluorescent display bias supplies, TFT-LCD bias supplies, and automotive engine control units.
