The device can operate with input voltages higher than, equal to, or lower than the output voltage making the product suitable for single lithium-Ion, multicell alkaline or NiMH applications where the output voltage is within the battery voltage range. The integrated low-RDS(on) N-channel and P-channel MOSFET switches contribute to its high efficiency. The mode pin allows the selection between auto mode and forced PWM mode thus taking benefit either of lower power consumption or better...
