LT1930AES5#TRMPBF

Overview

The LT1930AES5#TRMPBF is a synchronous step-up DC/DC converter manufactured by Analog Devices Inc., housed in a TSOT-23-5 package. It operates with an input voltage range of 2.45 V to 16 V and delivers up to 1 A switch current. The device features a fixed 2.2 MHz switching frequency, enabling the use of compact external components. It supports adjustable output voltages from 2.45 V to 36 V. Key electrical parameters include a shutdown supply current of less than 1 µA and an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates a high-efficiency synchronous rectifier architecture within a minimal footprint.
• Utilizes a fixed 2.2 MHz switching frequency to minimize passive component size.
• Includes internal soft-start functionality to limit inrush current during startup.
• Features a low-power shutdown mode for extended battery life in portable applications.

Applications

• Battery-powered portable instrumentation
• Cellular phone power management
• Handheld computing devices
• Industrial sensor nodes

Procurement Notes

Verify the specific suffix #TRMPBF indicates tape-and-reel packaging when sourcing. Confirm the 'A' grade designation matches required performance tolerances. Ensure the TSOT-23-5 footprint aligns with PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or thermal derating curves prior to final procurement.

Selection Notes

Select this component when space-constrained designs require a non-synchronous boost topology alternative or when specific efficiency characteristics at light loads are prioritized over maximum current capability. Compare against the standard LT1930ES5 if the lower 1.2 MHz frequency is acceptable for larger inductor usage. Evaluate thermal dissipation requirements based on the expected load current and ambient temperature conditions within the target enclosure.

Part Context

This part belongs to the LT1930 family of high-efficiency step-up converters designed for small form-factor applications. It serves as the higher-speed variant within the series, offering improved transient response compared to the base model. The family is characterized by its ability to generate regulated outputs from single-cell lithium-ion or alkaline battery sources efficiently.

Replacement Considerations

LT1930ES5#TRPBF: Base frequency variant (1.2 MHz). LT1931AES5#TRPBF: Inverting topology alternative.
