Overview
The LT1304CS8#PBF 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 delivers up to 1 A output current. The device utilizes a boost topology with a fixed switching frequency of 300 kHz. Quiescent current is specified at 120 µA, supporting low-power applications. It features an adjustable output voltage and includes a shutdown function for power management. The component is housed in an SOIC-8 surface-mount package and is rated for operation between 0°C and +70°C.
Feature Summary
- Integrates a low-battery detector for monitoring source conditions
- Utilizes Burst Mode operation for high efficiency at light loads
- Supports shutdown mode to minimize quiescent current consumption
Applications
- Small battery-operated systems requiring efficient step-up conversion
- Portable devices utilizing single-cell or multi-cell battery configurations
- Applications necessitating low standby current and compact form factors
Procurement Notes
Verify the specific suffix and package variant against the official Analog Devices datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and lead times through authorized distributors, as availability may vary. Cross-reference the manufacturer part number with ordering information to avoid discrepancies in pinout or electrical specifications during procurement.
Selection Notes
Select this component when an adjustable boost converter with integrated low-battery detection is required. Ensure the input voltage range aligns with the battery source characteristics. Consider the 1 A output capability and 300 kHz switching frequency for thermal and EMI constraints. Verify that the SOIC-8 package fits the PCB layout constraints compared to other available packages in the series.
Part Context
This part belongs to the LT1304 series of micropower high-efficiency DC/DC converters. It shares architectural similarities with the LT1303 but offers higher output current capabilities. The series is designed for portable electronics where battery life and space are critical. Other variants in the family include fixed-output versions and different packaging options to suit diverse application needs.
Replacement Considerations
LT1304CS8#TRPBF is a tape-and-reel version of the same component. LT1304CS8-5#PBF provides a fixed 5.05 V output instead of adjustable voltage. LT1303CS8#PBF offers similar functionality but with lower output current ratings. Verify electrical parameters and package dimensions before substitution.
