DESCRIPTION
The AIC2359 is a dual output, low-noise,
pulse-width-modulated (PWM), DC-DC step-
down converter. It powers logic and transmit-
ters in small wireless systems such as cellular
phones, communicating PDAs, and handy-
terminals.
The device features an internal synchronous
rectifier for high efficiency; it requires no exter-
nal Schottky diode. Internally fixed-frequency
1.5MHz operation provides easy post-filtering
and allows the use of small inductors and ca-
pacitors. The AIC2359 is ideally suited for Li-
Ion battery applications. PWM/PSM mode ex-
tends battery life by switching to a pulse-
skipping-modulated mode during light loads.
Shutdown mode places the device in standby,
reducing supply current to under 1µA..
Other features of the AIC2359 include high ef-
ficiency, soft start, over temperature protection,
and over current protection. It is available in a
space-saving
12-pin
DFN.
