描述 Description
The RT7255 is a simple, easy-to-use, 1.5A synchronous step-down DC-DC converter with an input supply voltage range of 4.3V to 18V. The device build-in an accurate 0.6V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in a TSOT-23-8 package.
The RT7255 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 RT7255A operates in automatic PSM that maintains high efficiency during light load operation. The RT7255C operates in Forced PWM that helps meet tight voltage regulation accuracy requirements.
The RT7255 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 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 RT7255 is offered in a TSOT-23-8 package.
