Conv DC-DC Single Step Up 0.9V to 5.5V 6-Pin SOT-23 T/R
Manufacturer Part #: AIC3415AGG6TR
Alternate Part #: AIC3415AGG6TR
The AIC3415 is a synchronous step-up DC/DC converter. 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.
