LT1303IS8#PBF

Overview

The LT1303IS8#PBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc., housed in an 8-lead SOIC package. It operates with an input voltage range of 1.8V to 6V and delivers up to 700mA output current. The device utilizes Burst Mode operation for high efficiency and features a low quiescent current of 120µA, reducible to 10µA via shutdown. It includes a low-battery detector and supports adjustable output voltages up to 25V.

Feature Summary

Burst Mode operation ensures high efficiency in small, low-voltage battery-powered systems
Integrated low-battery detector provides an open-collector output when input voltage drops below a preset level
On-chip NPN power switch offers low saturation voltage at high switch currents
Shutdown pin significantly reduces quiescent current consumption

Applications

Small, low-voltage battery-operated systems
EL panel drivers
Portable electronic devices requiring efficient step-up conversion

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging versus #TRPBF for reel packaging. Confirm RoHS compliance status as documentation may vary. Ensure the IS8 variant matches the required industrial temperature range specifications before finalizing procurement orders.

Selection Notes

Select this component for applications requiring micropower step-up conversion from single-cell or multi-cell batteries. Consider the LT1303-5 if a fixed 5V output is preferred over the adjustable version. Evaluate the LT1305 or LT1302 if higher output currents are necessary for the design requirements.

Part Context

The LT1303 belongs to a family of micropower high-efficiency DC/DC converters designed for space-constrained portable electronics. It complements other regulators like the LT1307 and LT1305, offering a balance of low standby current and moderate output capability within an 8-lead SOIC footprint.
