High Efficiency 1MHz, 1.8A Boost Regulator CE8309 Series  INTRODUCTION: The CE8309 is a high efficiency boost switching regulator designed for single cell lithium or two cells alkaline, NiMH, or NiCd battery powered applications. It generates an output voltage of up to 5.5V from an input voltage as low as 1.6V. Ideal for applications where space is limited, it switches at 1MHz, allowing the use of tiny, low cost and low profile external components, minimizes solution footprint. Its internal 1.8A, 100mΩ 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. Internal frequency compensation is designed to accommodate ceramic output capacitors, further reducing noise.
