Overview
The LT1304CS8-5#TRPBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 1.5 V to 8 V and provides a fixed regulated output of 5.05 V. The device delivers up to 200 mA of output current while maintaining a low quiescent current of 120 µA. It utilizes a boost topology within an SOIC-8 surface-mount package. The component supports a shutdown function and functions reliably across an operating temperature range from 0°C to +70°C.
Feature Summary
- Micropower step-up conversion utilizing Burst Mode operation for high efficiency in battery-powered systems
- Integrated low-battery detector for monitoring supply conditions
- Shutdown capability to minimize power consumption during inactive periods
Applications
- Small, low-voltage battery-operated systems
- Portable electronic devices requiring efficient voltage boosting
- Applications necessitating low quiescent current operation
Procurement Notes
Verify the specific suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Confirm RoHS compliance details directly from the manufacturer datasheet. Ensure the part number matches the exact fixed 5V variant required for your design specifications.
Selection Notes
Select this component when a fixed 5V output is required from a single-cell or dual-cell battery source. Consider the 120 µA quiescent current limit for standby applications. Verify that the 200 mA output current meets the load requirements. Compare against the adjustable LT1303 if variable output voltages are needed instead.
Part Context
This part belongs to the LT1303/LT1304 family of micropower high-efficiency DC/DC converters. While the LT1303 offers adjustable output, the LT1304 provides a fixed output option. Both utilize similar Burst Mode technology and share the SOIC-8 package form factor for compact circuit board layouts.
Replacement Considerations
The LT1303CS8-5#TRPBF serves as a functional equivalent within the same family offering identical fixed 5V output characteristics.
