It is also used in fuel cell or solar cell powered devices where the capability of handling low input voltages is essential.
Possible output currents depend on the input to output voltage ratio.
The devices provide output currents of up to 600 mA at a 5-V output, while using a single-cell LiIon or Li-Polymer battery and discharges it down to 2.
6 V.
The boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous rectification to obtain maximum efficiency.
At low load currents, the converter enters the Power Save mode ...
