6V 1A, ACOT® Buck Converter in Thin SOT-563 Package


Update Alert Share

The RT5760A/B/C/D is a simple, easy-to-use, 1A synchronous step-down DC-DC converter with an input supply voltage range from 2.5V to 6V. The device build-in an accurate 0.6V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in a SOT-563 (FC) package.

The RT5760A/B/C/D 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. The RT5760A/C operate in automatic PSM that maintain high efficiency during light load operation. The RT5760B/D operate in Forced PWM that help to meet tight voltage regulation accuracy requirements.

The RT5760A/B/C/D senses both FETs current for a robust over-current protection. The device features cycle-by-cycle current limit protection and prevent the device from the catastrophic damage in output short circuit, over current or inductor saturation. 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 to provide safe and smooth operation in all operating conditions.
