LT3580EDD#TRMPBF

Overview

The LT3580EDD#TRMPBF is a boost/inverting DC/DC converter featuring an integrated 2A switch. It operates with an input voltage range of 2.5V to 32V and supports output voltages up to 42V. The device utilizes a switching frequency between 200kHz and 2MHz, adjustable via an external resistor or synchronization pin. It includes soft-start functionality and is housed in an 8-lead MSOP package with an exposed pad.

Feature Summary

Integrates a 2A power switch for high-current capability
Supports boost, inverting, and SEPIC topologies
Includes programmable soft-start to limit inrush current
Allows external clock synchronization for noise management

Applications

Inverting regulator configurations converting positive inputs to negative outputs
Boost converters generating higher voltages from lower sources
SEPIC applications requiring wide input voltage ranges
Systems requiring synchronized switching frequencies

Procurement Notes

Verify the specific suffix 'EDD' corresponds to the 8-lead MSOP package with exposed pad. Confirm the '#TRMPBF' designation indicates tape and reel packaging with lead-free compliance. Ensure the manufacturer is Analog Devices Inc., formerly Linear Technology, to guarantee component authenticity and datasheet alignment.

Selection Notes

Select this component when a single IC must support multiple DC/DC topologies including boost and inverting modes. The 2A switch rating suits moderate load requirements. Consider the 200kHz to 2MHz frequency range for balancing efficiency and component size. Verify that the 32V maximum input voltage aligns with the system's supply constraints.

Part Context

This part belongs to the LT3580 family of mixed-signal power management ICs. It is designed for applications requiring flexible topology selection without increasing bill of materials complexity. The device integrates control logic, oscillators, and drivers into a compact surface-mount package.
