Overview
The LT1615IS5-1#TRMPBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 1V to 15V and provides an adjustable output voltage from 1.23V up to 34V. The device features a typical quiescent current of 20µA and supports a switch current of 75mA. It utilizes a TSOT-23-5 package and offers an adjustable switching frequency. The component is rated for industrial operating temperatures between -40°C and +85°C.
Feature Summary
- Supports boost and SEPIC topologies for flexible power conversion
- Features low quiescent current for extended battery life in portable applications
- Includes shutdown capability to minimize standby power consumption
Applications
- Portable electronic devices requiring efficient power management
- Battery-powered systems utilizing single-cell lithium-ion or alkaline sources
- Industrial equipment operating within specified temperature ranges
Procurement Notes
Verify the specific suffix #TRMPBF indicates tape and reel packaging when sourcing. Confirm availability status as supply may be limited or subject to factory special orders. Ensure compatibility with surface-mount assembly processes given the TSOT-23-5 form factor. Cross-reference official datasheets for exact electrical tolerances before finalizing procurement specifications.
Selection Notes
Select this component when designing circuits requiring high efficiency from low input voltages. The adjustable frequency allows optimization for external component size versus noise performance. Consider the 75mA switch current limit for load requirements. Verify that the required output voltage falls within the 1.23V to 34V adjustable range defined by the feedback network.
Part Context
This part belongs to the LT1615 series of micropower switching regulators. It is designed for space-constrained applications due to its small TSOT-23-5 package. The series is characterized by low standby current and wide input voltage ranges, making it suitable for various portable and industrial power solutions.
Replacement Considerations
Consult official documentation for direct pin-compatible substitutes within the LT1615 family. Verify electrical parameters such as switch current and quiescent current match design requirements when considering alternative models.
