AS1332 Datasheet (austriamicrosystems AG) - 650mA Step-Down DC-DC Converter

AS1332, 650mA Step-Down DC-DC Converter

The AS1332 is a step-down DC-DC converter designed to power radiofrequency (RF) power amplifiers (PAs) from a single Li-Ion battery.

The device also achieves high-performance in mobile phones and similar RF PA applications.

The AS1332 steps down an input voltage of 2.7V to 5.5V to output voltages ra
