The RT6372A/B is a simple, easy-to-use, 2A synchronous step-down DC-DC converter with an input supply voltage range of 4.5V to 17V. The device possesses an accurate reference voltage and integrates low R<sub>DS(ON)</sub> power MOSFETs to achieve high efficiency. </p>The RT6372A/B adopts Advanced Constant On-Time (ACOT<sup>®</sup>) 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 RT6372A operates in automatic PSM that maintains high efficiency during light load operation. The RT6372B operates in Forced PWM that helps meet tight voltage regulation accuracy requirements. </p>The RT6372A/B senses both FETs current for a robust over-current protection (OCP). The device 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 (OTP) to provide safe and smooth operation in all operating conditions.</p>
