Chipower CE8320
The CE8320 is a high efficiency boost switching regulator especially designed for single cell Li-ion /Li-Pol battery powered applications. It generates an output voltage of up to 5.5V from an input voltage as low as 1.6V. Its internal 4A, 70mΩ NMOS switch provides high efficiency even at heavy load, while the constant frequency, current mode architecture results in low, predictable output noise that is easy to filter.FEATURES
