LT1617ES5#TRPBF

Overview

The LT1617ES5#TRPBF is a Cuk switching regulator IC manufactured by Analog Devices Inc., housed in a TSOT-23-5 package. It operates with an input voltage range of 1.2V to 15V and provides a negative adjustable output voltage ranging from -1.2V to -34V. The device supports a maximum switch current of 300mA and features one output channel. Designed for surface mount installation, it functions within a temperature range of 0°C to 70°C.

Feature Summary

Implements Cuk topology for efficient positive-to-negative voltage conversion
Supports wide input voltage range from 1.2V to 15V
Provides adjustable negative output voltage capability

Applications

Li-Ion battery powered systems requiring negative rail generation
Inverting DC/DC converter circuits
Charge pump applications for negative voltage supply

Procurement Notes

Verify the specific suffix #TRPBF against official Analog Devices documentation to confirm tape and reel packaging specifications. Ensure the component matches the required thermal and electrical ratings for the target application environment. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and sourcing channels before procurement.

Selection Notes

Select this component when a compact solution for generating negative voltages from a single positive source is required. The Cuk topology offers continuous input and output currents, which may reduce filtering requirements compared to other topologies. Consider the 300mA switch current limit and the specific input voltage range constraints during circuit design.

Part Context

This part belongs to the LT1615/LT1617 family of micropower switching regulators designed for space-constrained applications. These devices integrate power switches and control logic into small packages, enabling high-efficiency DC/DC conversion in portable electronics and battery-operated systems where board area is limited.
