DIO54312

描述

The DIO54312 is a high-efficiency, high-frequency synchronous step-down DC-DC regulator IC capable of delivering up to 3 A output currents. The DIO54312 operates over a wide input voltage range from 4.5 V to 30 V and integrates the main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The output voltage can be regulated to as low as 0.6 V. The COT architecture with pseudo-fixed switching frequency operation provides a fast transient response and eases loop stabilization. The DIO54312 operates in pulse skip mode where the device maintains a high efficiency during light load operation. Protection features include overcurrent protection and thermal shutdown. The DIO54312 requires a minimal number of readily-available, standard, external components and is available in a space-saving TSOT23-6 package.
