CategoryPower Management - DC2DC GROUP
The WD1304E30 is a high efficiency,760 kHz switch frequency, synchronous step-down DC-DC converter with delivering 3A current capability. The WD1304E30 operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS (ON) to minimize the conduction loss.
The WD1304E30 applies Constant-on-time (COT) control mode which provides very fast load transient response and easy loop design. The WD1304E30 integrates full protections features including short-circuit protection, over-current protection, under voltage protection and thermal shutdown to make the part operating safely.
The WD1304E30 is available in SOT-23-6L package. Standard product is Pb-free and Halogen-free.
