LM5168FDDAR Integrated Circuit Chip Step-Down Converter With Fly-Buck™Converter Capability

LM5168FDDAR Integrated Circuit Chip Step-Down Converter With Fly-Buck™Converter Capability

Product Description Of LM5168FDDAR

LM5168FDDAR synchronous buck converters is designed to regulate over a wide input voltage range, minimizing the need for external surge suppression components. A minimum controllable on time of 50ns facilitates large step-down conversion ratios, enabling the direct step-down from a 48V nominal input to low-voltage rails for reduced system complexity and design cost. LM5168FDDAR operates during input voltage dips as low as 6V, at nearly 100% duty cycle if needed, making the device an excellent choice for wide input supply range industrial and high cell count battery pack applications.
