AS1324-BTTT-12

Overview

The AS1324-BTTT-12 is a synchronous buck converter from the AS1324 series, manufactured by ams OSRAM. It operates at a constant frequency of 1.5 MHz and delivers an output current of 600 mA. The device accepts an input voltage range of 2.7 V to 5.5 V and provides a fixed output voltage of 1.2 V. It features a low quiescent current of 30 µA with no load and reduces to ≤1 µA in shutdown mode. The component utilizes a TSOT23-5 package for surface mount installation.

Feature Summary

High-efficiency synchronous design eliminates the need for external Schottky diodes
Automatic powersave operation optimizes performance under light loads
Integrated thermal protection safeguards against overheating conditions

Applications

Single Li-Ion battery-powered applications
Portable consumer electronics
Mobile devices requiring efficient power management

Procurement Notes

Verify the specific suffix BTTT-12 to confirm the fixed 1.2 V output voltage variant. Ensure compatibility with the TSOT23-5 package dimensions during PCB layout. Confirm availability status as supply conditions may vary. Cross-reference with official datasheets for absolute maximum ratings before integration into final designs.

Selection Notes

Select this component for applications requiring high efficiency and minimal external components. The 1.5 MHz switching frequency allows for smaller passive components. Consider the 2.7 V minimum input voltage when designing for single-cell lithium-ion systems. The low shutdown current is suitable for battery-operated devices requiring extended standby times.

Part Context

The AS1324 series represents a family of high-efficiency synchronous DC/DC converters designed for portable electronics. This specific model belongs to the adjustable and fixed-voltage versions within the series. The product line emphasizes compactness and energy efficiency, targeting mobile and wearable technology markets where space and power consumption are critical constraints.
