Overview
The LT1303CS8#TRPBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. 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 in battery-powered systems. Key electrical parameters include a quiescent current of 120µA, a switching frequency of 155kHz, and an adjustable output voltage capability up to 25V. It features a low-battery detector and shutdown functionality, housed in an SOIC-8 surface-mount package.
Feature Summary
- Integrates a low-battery detector for monitoring supply conditions
- Utilizes Burst Mode operation to maintain high efficiency at light loads
- Provides adjustable output voltage control via external feedback components
- Includes a shutdown pin to minimize power consumption during standby
Applications
- Small low-voltage battery-operated systems
- Portable electronic devices requiring efficient step-up conversion
- Micropower applications with strict current constraints
Procurement Notes
Verify the specific suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and RoHS compliance status. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity. Confirm that the SOIC-8 package variant matches your PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits requiring a compact boost converter with minimal quiescent current. Ensure the application demands an input voltage between 1.8V and 6V. Verify that the required output voltage does not exceed the 25V limit and that the load current remains within the 700mA specification. Consider the thermal performance of the SOIC-8 package for your enclosure design.
Part Context
This part belongs to the LT1303 series of micropower high-efficiency DC/DC converters. The series includes fixed 5V variants like the LT1303-5 and adjustable versions. These converters are designed specifically for portable applications where battery life is critical. The family shares common architectural features such as Burst Mode operation and integrated low-battery detection capabilities.
FAQ
What is the maximum adjustable output voltage?
The LT1303 can supply an adjustable output voltage up to 25V.
How does the device achieve high efficiency at light loads?
