AS1324-BTTT-AD

Overview

The AS1324-BTTT-AD is a high-efficiency, constant-frequency synchronous buck converter manufactured by ams OSRAM. It operates within an input voltage range of 2.7V to 5.5V and delivers an output current of 600mA. The device features a fixed switching frequency of 1.5MHz and supports adjustable output voltages via external resistors. Key electrical parameters include a typical supply current of 30µA with no load and a shutdown mode supply current of ≤1µA. It utilizes a TSOT23-5 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

High efficiency up to 96% through internal synchronous switching
Eliminates the need for an external Schottky diode
Supports automatic powersave operation for low quiescent current
Includes thermal protection mechanisms

Applications

Single Li-Ion battery-powered applications
Portable electronic devices requiring efficient power management
Systems utilizing single-cell lithium-ion batteries

Procurement Notes

Verify the specific suffix 'AD' against official datasheets to confirm it denotes the adjustable output version in the TSOT23-5 package. Ensure compatibility with required external resistor values for target voltage settings. Confirm RoHS compliance status and moisture sensitivity levels prior to integration into manufacturing processes.

Selection Notes

Select this component for designs requiring high efficiency and minimal external components in single-cell battery systems. The adjustable output capability allows flexibility in setting precise voltage levels. Consider the 1.5MHz switching frequency for balancing component size and efficiency. Verify that the 600mA output current meets the load requirements of the target application.

Part Context

The AS1324 belongs to a series of synchronous DC/DC converters designed for portable electronics. It is part of the broader portfolio of power management integrated circuits offered by ams OSRAM. This specific model focuses on optimizing performance for single-cell lithium-ion battery applications where space and efficiency are critical constraints.
