Chipower CE8313
The CE8313 is a high efficiency boost switching regulator especially designed for single cell lithium battery powered applications. It generates an output voltage of up to 5.5V from an input voltage as low as 2.7V. Its internal 2.5A, 80mΩ 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
