LP3219
1.5MHz, 2A Step-Down Converter
概述
The LP6498H is a synchronous step-down regulator from a high voltage input supply. Operating with an input voltage range from 8V to 30V and 1.2A continuous output current. The converter integrates a main switch and a synchronous rectifier for high efficiency without an external schottky diode.LP6498H requires a minimum number of readily available standard external components, over current protection and thermal shutdown, output short circuit protection.The LP6498H converters are available in the industry standard SOP-8 and DIP-8 packages.
