The AIC3415 is a synchronous step-up DC/DC con-
verter.
There are two options for AIC3415: automatic
PWM/PSM version (AIC3415), and forced PWM ver-
sion (AIC3415A). The automatic PWM/PSM version
enters PSM from PWM automatically when load de-
creases. The goal is to improve efficiency and reduce
quiescent current; the forced PWM version keeps the
same operating frequency even when it operates in
light load. This guarantees low output ripple and noise.
The AIC3415 provides a complete power supply solu-
tion for products powered by one or two Alkaline,
Ni-Cd, Ni-MH or Li-Lon battery cells. It stays in opera-
tion with supply voltages down to 0.5V. The imple-
mented boost converter uses an internal synchronous
rectifier to obtain maximum efficiency.
A low-EMI mode is implemented to reduce ringing and
in effect lower radiated electromagnetic energy when
the converter enters the discontinuous conduction
mode.
