RT6214B - 3A Buck Converter

Download the RT6214B datasheet PDF. This datasheet also covers the RT6214A variant, as both devices belong to the same 3a buck converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The RT6214A/B is a simple, easy-to-use, 3A synchronous step-down DC-DC converter with an input supply voltage range of 4.5V to 18V.

Key Features

  • cycle-by-cycle current limit protection and prevent the device from the catastrophic damage in output short circuit, over current or inductor saturation. The RT6214A/B SOT-23-6 series built-in soft-start function prevents inrush current during start-up and the SOT-23-8 series offers programmable start-up by connecting a capacitor at external SS pin. The device also includes input under-voltage lockout, output under-voltage protection, and over-temperature protection (thermal shutdown) to provide.

RT6214A/B 18V Input, 3A, ACOTTM Buck Converter in 6 and 8 Pin TSOT-23 with Both FETs OC Protection General Description The RT6214A/B is a simple, easy-to-use, 3A synchronous step-down DC-DC converter with an input supply voltage range of 4.5V to 18V. The device integrates low RDS(ON) power MOSFETs to achieve high efficiency in a SOT-23 package and build-in accurate reference voltage (0.765V or 0.8V by product options). The RT6214A/B adopts Advanced Constant On-Time (ACOTTM) 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 RT6214A operates in automatic PSM that maintains high efficiency during light load operation.
