Overview
The LT1615ES5-1#TRPBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. It operates within an input voltage range of 1 V to 15 V and provides a single adjustable output up to 34 V. The device supports a maximum switch current of 75 mA with a typical quiescent current of 20 uA. It utilizes a Boost or SEPIC topology and features an adjustable switching frequency. The component is housed in a compact SOT-23-5 package, suitable for surface mount installation.
Feature Summary
- Integrates a micropower boost converter capable of operating from very low input voltages down to 1 V.
- Features a shutdown mode that significantly reduces power consumption for battery-powered applications.
- Supports both boost and SEPIC topologies to accommodate various input-to-output voltage requirements.
Applications
- Portable electronic devices requiring efficient voltage step-up from single-cell sources
- Battery-operated systems needing extended runtime through low quiescent current operation
- Applications utilizing lithium-ion or alkaline batteries as primary power sources
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the manufacturer part number matches Analog Devices Inc. specifications exactly. Check RoHS compliance documentation for environmental regulatory adherence. Ensure the SOT-23-5 package dimensions align with your PCB footprint design requirements before finalizing procurement orders.
Selection Notes
Select this component when input voltages start as low as 1 V and high output voltages are required. The adjustable switching frequency allows optimization for efficiency versus component size. Consider the 75 mA switch current limit against peak load demands. The SOT-23-5 package offers a small footprint suitable for space-constrained portable designs compared to larger regulator packages.
Part Context
This part belongs to the LT1615 series of micropower step-up converters. The ES5-1 designation specifies the commercial temperature grade and the specific pin configuration variant within the TSOT-23-5 package family. It is distinct from automotive-grade variants like the IS5 series which share similar electrical characteristics but differ in reliability standards.
Replacement Considerations
LT1615IS5-1#TRMPBF shares identical electrical specifications but is rated for industrial temperature ranges and may have different packaging options.
