Datasheet
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
V
CON
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 fixed-
frequency 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. Only three
external components are required, an inductor and two
ceramic capacitors.
The AS1332 is available in a 8-pin WL-CSP.
