The RT6236A/B is a high-performance 650kHz, 6A stepdown
regulator with internal power switches and
synchronous rectifiers. It features quick transient response
using its Advanced Constant On-Time (ACOTTM) control
architecture that provides stable operation with small
ceramic output capacitors and without complicated
external compensation, among other benefits. The input
voltage range is from 4.5V to 18V and the output is
adjustable from 0.7V to 8V. The proprietary ACOTTM control
improves upon other fast response constant on-time
architectures, achieving nearly constant switching
frequency over line, load, and output voltage ranges. Since
there is no internal clock, response to transients is nearly
instantaneous and inductor current can ramp quickly to
maintain output regulation without large bulk output
capacitance. The RT6236A/B is stable with and optimized
for ceramic output capacitors. With internal 51mΩ switches
and 18mΩ synchronous rectifiers, the RT6236A/B displays
excellent efficiency and good behavior across a range of
applications, especially for low output voltages and low
duty cycles.RT6236AHGQUF RT6236BHGQUF
