There are two options for AIC3415: automatic PWM/PSM version (AIC3415), and forced PWM version (AIC3415A).
The automatic PWM/PSM version enters PSM from PWM automatically when load decreases.
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 solution for products powered by one or two Alkaline, Ni-Cd, Ni-MH or Li-Lon battery cells.
It stays in operation with supply voltages down to 0.
5V.
The implemented 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.
