Overview
The LT3483IS6#TRMPBF is a micropower inverting DC/DC converter manufactured by Analog Devices Inc. It operates within an input voltage range of 2.5 V to 16 V and delivers up to 200 mA output current with a maximum negative output voltage of -38 V. The device features a fixed switching frequency of 150 kHz and a typical quiescent current of 40 uA. It supports shutdown functionality and functions reliably across an extended temperature range from -40°C to +85°C.
Feature Summary
- Integrates a Schottky diode for efficient inverting topology operation
- Provides adjustable current limit protection
- Includes a dedicated shutdown pin for power management
Applications
- Inverting power supply generation for sensor biasing
- Negative rail creation for operational amplifier circuits
- Power management in portable instrumentation systems
Procurement Notes
Verify the specific suffix TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with SMD/SMT assembly processes utilizing the TSOT-23-6 package. Cross-reference thermal performance requirements against the datasheet limits for the intended operating environment.
Selection Notes
Select this component when designing compact systems requiring a negative voltage rail from a single positive source. The low quiescent current makes it suitable for battery-powered applications. Verify that the required output current does not exceed the 200 mA limit under worst-case thermal conditions.
Part Context
This part belongs to the LT3483 series of micropower DC/DC converters. It is designed for space-constrained applications where efficiency and low standby current are critical. The TSOT-23-6 package allows for minimal footprint usage in dense PCB layouts.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Generic replacements may differ in thermal characteristics or control loop stability.
