www.DataSheet4U.com AS1332 1 General Description 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 ranging from 1.3V to 3.16V. Using a VCON analog input, the output voltage is set for controlling power levels and efficiency of the RF PA. The RF interferences are minimized due to the fixedfrequency PWM operation. The battery consumption is reduced to 0.01µA (typ.) during shutdown. Because of the high switching frequencies (2 MHz) tiny surface-mount components can be used. Additional to the small size the amount is also small.
