LT3483IDC#TRMPBF

Overview

The LT3483IDC#TRMPBF is a micropower inverting DC/DC converter manufactured by Analog Devices. It operates within an input voltage range of 2.5 V to 16 V and delivers up to 200 mA output current at -38 V. The device features a low quiescent current of 40 uA and a fixed switching frequency of 150 kHz. It is housed in a compact TSOT-23-6 package and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Inverting topology for generating negative voltages from positive sources
• Micropower operation with low standby current consumption
• Integrated Schottky rectifier for improved efficiency
• Compact surface-mount packaging for space-constrained designs

Applications

• Portable instrumentation requiring negative supply rails
• Battery-powered systems needing efficient voltage inversion
• Industrial control circuits with single-supply constraints

Procurement Notes

Verify the specific suffix TRMPBF indicates tape-and-reel packaging when ordering. Confirm the I-grade temperature rating aligns with your operational environment requirements. Ensure compatibility with the TSOT-23-6 footprint during PCB layout. Cross-reference the manufacturer's latest datasheet for any design revisions or recommended component values.

Selection Notes

Select this component when a negative voltage rail is required from a single positive source. Consider the 200 mA output limit for load requirements. Evaluate the 150 kHz switching frequency against EMI constraints. Compare thermal performance in the TSOT-23-6 package against higher-power alternatives if loads exceed specifications.

Part Context

This part belongs to the LT3483 series of micropower DC/DC converters. It shares functional similarities with other inverting regulators but offers specific integration of the Schottky diode. The series targets applications where size and quiescent current are critical design parameters.
