LT1617ES5-1#TRPBF

Overview

The LT1617ES5-1#TRPBF is a Cuk switching regulator IC manufactured by Analog Devices Inc., housed in a TSOT-23-5 package. It provides a single negative adjustable output ranging from -1.2V to -34V with a maximum switch current of 300mA. The device operates with an input voltage between 1.2V and 15V. Key electrical characteristics include a shutdown feature and operation within a temperature range of 0°C to 70°C.

Feature Summary

• Implements Cuk topology for continuous input and output current, reducing electromagnetic interference requirements.

Applications

• Negative voltage generation for sensor biasing
• Power supply stages requiring low ripple negative rails

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging compliant with RoHS standards. Confirm the -1 variant designation matches the required negative output configuration. Ensure the TSOT-23-5 footprint aligns with the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a negative output voltage is required from a positive input source. The Cuk topology suits applications needing low input noise sensitivity. Verify that the 300mA switch current capability meets the load demands and that the operating temperature range covers the environmental conditions.

Part Context

This part belongs to the LT1617 family of micropower switching regulators. It shares the TSOT-23-5 form factor with other compact power management solutions from Analog Devices, designed for space-constrained portable electronics and battery-powered systems requiring efficient DC/DC conversion.

Replacement Considerations

LT1617ES5#TRMPBF serves as a compatible alternative within the same series, offering identical functional specifications but potentially differing in packaging format or reel specifications.
