LT8330JS6#TRMPBF

Overview

The LT8330JS6#TRMPBF is a current-mode DC/DC converter from Analog Devices Inc., designed for boost, SEPIC, and inverting topologies. It integrates a 1A switch rated for 60V and operates with a fixed switching frequency of 2MHz. The device accepts an input voltage range from 3V to 40V and supports adjustable output voltages starting from 1.6V or -0.8V. Housed in a TSOT-23-6 package, it features low quiescent current consumption, integrated soft-start, and frequency foldback functions to manage inductor current during startup.

Feature Summary

• Supports boost, SEPIC, and inverting converter configurations using a single feedback pin.
• Integrates a high-voltage 60V switch capable of delivering up to 1A of output current.
• Incorporates frequency foldback functionality to control inductor current during start-up conditions.

Applications

• Battery-powered systems requiring step-up or inverted voltage rails
• Industrial applications needing isolated or non-isolated negative supply generation
• Portable electronics utilizing small form-factor power solutions

Procurement Notes

Verify the specific suffix JS6 against official Analog Devices documentation to confirm temperature grade and packaging specifications. Ensure compatibility with the target PCB footprint for the TSOT-23-6 package. Cross-reference the datasheet for thermal performance requirements under maximum load conditions before finalizing procurement.

Selection Notes

Select this component when a compact solution is required for generating positive or negative outputs from a 3V to 40V source. The 2MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 60V switch rating for applications with potential input voltage transients exceeding standard 40V limits.

Part Context

This part belongs to the LT8330 family of low IQ converters. It shares architectural similarities with other members like the LT8330ES6 but differs in specific electrical characteristics and operating temperature ranges defined by the suffix. The family is designed to minimize external component count while maintaining stable operation across wide input and output voltage variations.

Replacement Considerations

Consult official substitution guides for equivalent parts within the LT8330 series or alternative manufacturers offering similar 60V, 1A boost/SEPIC controllers. Verify pinout compatibility and thermal dissipation capabilities before replacing.
