Richtek RT8097ALGE

Step-DownБак2.7V6V2A

Overview

The RT8097ALGE is a simple, easy-to-use, 2A synchronous step-down DC-DC converter with an input supply voltage range of 2.7V to 6V. The device build-in an accurate 0.6V (typ.) reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in a SOT-23-5 and SOT-23-6 packages. The RT8097ALGE adopts Current Mode Constant On-Time (CMCOT) control architecture to provide an ultrafast transient response with few external components and to operate in nearly constant switching frequency over the line, load, and output voltage range. The RT8097ALGE operates in automatic PSM that maintains high efficiency during light load operation. The RT8097ALGE senses low-side FETs current for a robust over-current protection. It features cycle-by-cycle current limit protection and prevent the device from the catastrophic damage in output short circuit, over current or inductor saturation. An internally adjustable soft-start function prevents inrush current during start-up. The device also includes input under-voltage lockout, output under-voltage protection, and over-temperature protection (thermal shutdown) to provide safe and smooth operation in all operating conditions. The RT8097ALGE is offered in a SOT-23-5 and SOT-23-6 packages.
