LT1935ES5#TRPBF

Overview

The LT1935ES5#TRPBF is a synchronous step-up DC/DC converter manufactured by Analog Devices Inc., housed in a TSOT-23-5 surface-mount package. It operates with an input voltage range of 2.1 V to 16 V and delivers up to 2 A of switch current. The device features a fixed switching frequency of 1.2 MHz, allowing for the use of small external components. It provides a maximum output voltage of 38 V from a single output channel. Quiescent current is specified at 1 uA, while operating supply current is 3 mA. The component functions within a temperature range of -40°C to +85°C and includes shutdown capability.

Feature Summary

• Synchronous boost topology enables high efficiency in compact designs
• Integrated power switch supports high output current capabilities
• Fixed 1.2 MHz switching frequency minimizes passive component size
• Ultra-low quiescent current extends battery life in standby modes

Applications

• Portable instrumentation requiring high power density
• Battery-powered systems needing voltage step-up
• Industrial control modules with limited board space
• Consumer electronics utilizing lithium-ion or alkaline cells

Procurement Notes

Verify component authenticity through authorized distribution channels due to restricted availability status noted by major distributors. Confirm RoHS compliance documentation matches the specific manufacturing batch. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet prior to assembly. Cross-reference ordering part numbers with final suffixes to guarantee correct packaging configuration.

Selection Notes

Select this regulator when space constraints necessitate a TSOT-23-5 footprint alongside high current requirements. The 1.2 MHz frequency allows smaller inductors compared to lower-frequency alternatives. Evaluate thermal performance under maximum load conditions given the small package size. Consider input voltage ranges relative to source batteries or rails to ensure operation within the 2.1 V minimum threshold.

Part Context

This component belongs to the LT1935 series of synchronous boost converters designed for high-efficiency power management. It complements other Analog Devices PMIC solutions by offering a compact form factor suitable for modern portable devices. The series focuses on balancing performance metrics with physical size reduction, addressing trends in miniaturized electronic equipment design.
