LT1930AES5#TRPBF

Overview

The LT1930AES5#TRPBF is a high-efficiency step-up DC/DC converter manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 2.2 MHz and supports an input voltage range from 2.45 V to 16 V. The device delivers a maximum switch current of 1 A and can generate output voltages up to 36 V. It features a TSOT-23-5 package, ensuring a compact footprint for space-constrained designs. The component functions within a temperature range of 0°C to 70°C and includes shutdown capabilities.

Feature Summary

• Integrates a 1A power switch with low saturation voltage for efficient energy transfer
• Utilizes a 2.2 MHz fixed switching frequency to minimize external passive component size
• Supports multiple topologies including boost, inverting, SEPIC, and flyback configurations
• Features ultra-low shutdown current to extend battery life in portable applications

Applications

• Battery-powered portable instrumentation
• Cellular phone and mobile communication devices
• Handheld data terminals
• Medical equipment requiring compact power solutions

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm that the AES5 variant meets the required industrial or commercial temperature specifications for your application environment. Ensure compatibility with the intended PCB layout guidelines provided in the official datasheet to maintain performance stability.

Selection Notes

Select this component when a small form factor is critical alongside moderate current requirements. The 2.2 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the LT1930ES5 if a 1.2 MHz frequency is preferred for noise-sensitive applications, or the LT1930A series for general availability checks.

Part Context

This part belongs to the LT1930 family of ThinSOT step-up converters designed for high power density. It replaces larger legacy regulators by integrating the power switch and control logic into a five-pin surface-mount package. The series is engineered to provide complete regulator solutions in minimal board area.

Replacement Considerations

LT1930ES5#TRPBF offers identical functionality with a 1.2 MHz switching frequency.
