Overview
The LT1615ES5#TRMPBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. It operates within an input voltage range of 1V to 15V and provides a maximum output voltage of 34V. The device delivers a switch current of 300mA with a typical quiescent current of 20uA. It features an adjustable switching frequency and supports Boost and SEPIC topologies. Packaged in a TSOT-23-5 surface-mount case, it functions as a positive, adjustable single-output regulator.
Feature Summary
- Supports Boost and SEPIC converter topologies for flexible power conversion
- Micropower operation with low quiescent current consumption
- Adjustable switching frequency allows optimization for efficiency or size
- Integrated shutdown control for power management
Applications
- Portable electronic devices requiring efficient voltage step-up
- Battery-powered systems utilizing lithium-ion power supplies
- Applications needing SEPIC topology for varying input voltages
Procurement Notes
Verify the specific suffix #TRMPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the component matches the TSOT-23-5 package dimensions. Check RoHS compliance status through official documentation before integration into production designs.
Selection Notes
Select this component for applications requiring a compact solution with high efficiency at light loads. The adjustable frequency feature permits trade-offs between external component size and noise performance. Consider the 300mA switch current limit when designing for higher load requirements.
Part Context
This part belongs to the LT1615 series of micropower step-up converters. It is designed for portable electronics where battery life and board space are critical constraints. The series offers various package options and configurations to suit different system architectures.
Replacement Considerations
LT1615ES5-1#TRPBF is a related variant within the same family. Verify if the -1 suffix alters internal parameters or pinout compatibility before substitution.
