DIO69319

描述

The DIO69319 is a high-efficiency, high-frequency synchronous step-down DC-DC regulator ICs capable of delivering up to 3 A output currents. The DIO69319 family operates over a wide input voltage range from 4.5 V to 24 V and integrates the main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The pure COT architecture with pseudo-fixed switching frequency operation provides a fast transient response and eases loop stabilization. Protection features include over-current protection and thermal shutdown. The DIO69319 always operates in continuous conduction mode, which reduces the output ripple voltage under light load compared to discontinuous conduction mode. The DIO69319 is stable, with an extremely low ESR and high capacitance. The DIO69319 requires a minimal number of readily-available, standard, external components and is available in a space-saving TSOT23-6 package.
