Overview
The AS1324-BTTT-18 is a high-efficiency, constant-frequency synchronous buck converter manufactured by ams OSRAM. It features an adjustable and fixed-voltage output configuration with a wide input voltage range from 2.7V to 5.5V. The device provides a maximum output current of 600mA and operates at a switching frequency of 1.5MHz. Key electrical parameters include a typical supply current of 30µA with no load, reducing to ≤1µA in shutdown mode. The internal reference voltage is set at 0.6V. The component is housed in a compact 5-pin TSOT-23 package, designed for minimal external component requirements.
Feature Summary
- High efficiency up to 96% with integrated synchronous switches
- Eliminates the need for an external Schottky diode
- Automatic powersave operation for low quiescent current
- Built-in thermal protection for enhanced reliability
Applications
- Single Li-Ion battery-powered applications
- Portable consumer electronics
- Mobile devices requiring efficient power management
Procurement Notes
Verify the specific part number against official ams OSRAM documentation to confirm availability and lifecycle status. Ensure that the selected variant matches the required fixed output voltage and package type for your design. Cross-reference with authorized distributors to validate authenticity and technical specifications before procurement.
Selection Notes
Select this component for designs requiring high efficiency and low standby current in single-cell lithium-ion systems. The fixed 1.8V output suits applications needing a stable regulated voltage without external resistor programming. Consider the TSOT-23 package size for space-constrained PCB layouts.
Part Context
The AS1324 series represents a family of synchronous DC/DC converters optimized for portable electronics. This specific model belongs to the standard versions offering fixed output voltages, distinguishing it from adjustable variants within the same product line.
Replacement Considerations
Consult cross-reference tools for compatible alternatives if this part is unavailable. Verify that substitute components match the input voltage range, output current capability, and package dimensions to ensure seamless integration.
