LT3483AEDC#TRMPBF

Overview

The LT3483AEDC#TRMPBF is an inverting micropower DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.5 V to 16 V and delivers a negative output voltage up to -38 V. The device provides an output current of 200 mA while maintaining a low quiescent current of 40 µA. It functions at a fixed switching frequency of 150 kHz and is housed in a TSOT-23-6 package. The component supports operation within a temperature range of -40°C to +85°C.

Feature Summary

• Inverting topology for generating negative supply rails from positive inputs
• Integrated Schottky diode eliminates external component requirements
• Micropower design ensures minimal standby current consumption

Applications

• Single-supply operational amplifier biasing
• RS-232 transceiver power supplies
• Data acquisition systems requiring dual polarity rails

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and thermal characteristics. Ensure the ordering code matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits that require a compact solution for generating negative voltages from a single positive source. Consider the 200 mA output capability and 150 kHz switching frequency for applications prioritizing size over high-frequency noise sensitivity. Evaluate the 40 µA quiescent current against system power budget constraints.

Part Context

This part belongs to the LT3483 family of inverting micropower DC/DC converters. It shares functional similarities with other Linear Technology (now Analog Devices) products designed for low-power inversion tasks. The ES6 or EDC suffix indicates specific package and temperature grade variations within the broader product line.
