LT1303CS8#PBF

Overview

The LT1303CS8#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 1.8 V to 6 V and delivers an adjustable output voltage up to 25 V at a maximum switch current of 700 mA. The device utilizes Burst Mode operation for high efficiency and maintains a quiescent current of 120 µA. A dedicated shutdown pin reduces standby current to 10 µA, while an integrated low-battery detector provides an open-collector output when the input voltage drops below a preset threshold.

Feature Summary

Integrates a low saturation voltage NPN power switch for efficient energy transfer
Features Burst Mode operation to maintain high efficiency across varying load conditions
Includes a low-battery detector with an open-collector output for system monitoring

Applications

Small battery-operated systems requiring high efficiency
EL panel drivers utilizing step-up conversion
Low-voltage portable electronic devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited supply status. Confirm RoHS compliance details as documentation indicates variable availability. Ensure the specific SOIC-8 package variant matches design requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring adjustable boost conversion from low input voltages. Compare against fixed-output variants like the LT1303CS8-5#PBF if a constant 5 V output is sufficient. Consider the LT1305 or LT1302 if higher output currents exceeding 700 mA are required for the target application.

Part Context

This part belongs to the LT1303 series of micropower high-efficiency DC/DC converters. The series includes both adjustable and fixed 5 V versions, available in PDIP and SO packages. These converters are designed specifically for small, low-voltage battery-operated systems where space and power consumption are critical constraints.
