LT3579EUFD#PBF Description

Short technical summary and product information.

The LT3579EUFD#PBF is a PWM DC/DC converter manufactured by Analog Devices, designed for robust power supply applications. It features a combined 6A power switch with a 42V rating, capable of handling output short circuits, input/output overvoltage, and overtemperature conditions.

 

This converter supports a wide input voltage range from 2.5V to 16V operating, with a 40V maximum transient rating. It can be configured as a Boost, SEPIC, Inverting, or Flyback converter. For example, it can generate 12V at 1.7A or -12V at 1.2A from a 5V input. The switching frequency can be set between 200kHz and 2.5MHz, and it can be synchronized to an external clock.

 

The LT3579EUFD#PBF is available in 20-lead TSSOP and 20-pin 4mm x 5mm QFN packages, suitable for surface mount applications. Its fault protection features make it ideal for local power supplies, VFD bias supplies, TFT-LCD bias supplies, and automotive engine control units.
