RT6264B Datasheet Buck Converter

Manufacturer: Richtek

Overview: RT6264A/B 18V Input, 4A, ACOT® Buck Converter with Both FETs OC Protection.

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

General Description

The RT6264A/B is a simple, easy-to-use, 4A synchronous step-down DC-DC converter with an input supply voltage range of 4.5V to 18V.

The device possesses an accurate 0.765V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency.

The RT6264A/B adopts Advanced Constant On-Time (ACOT® ) 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 to prevent the device from the catastrophic damage in output short circuit, over-current or inductor saturation conditions. A built-in 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 recommended junction temperature range is.
  • 40C.
