RT6217B Datasheet Step-down Converter

Manufacturer: Richtek

Overview: ® RT6217A/B 24V, 3A, 500kHz, ACOTTM Step-Down Converter in 8 Pin TSOT-23.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The RT6217A/B is a simple, easy-to-use, 3A synchronous step-down DC-DC converter with an input supply voltage range of 4.5V to 24V.

The device build-in an accurate 0.791V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in a TSOT-23-8 (FC) package.

The RT6217A/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.

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. An externally 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 RT6217A/B is offered in a TSOT23-8(FC) package. Fea.
