RT6353A/B
17V Input, 3A, ACOT® Buck Converter with Both FETs OC Protection
General Description
The RT6353A/B is a simple, easy-to-use, 3A 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 RDS(ON) power MOSFETs to achieve high efficiency.
The RT6353A/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. The RT6353A operates in automatic PSM that maintains high efficiency during light load operation. The RT6353B operates in Forced PWM that helps meet tight voltage regulation accuracy requirements.
