RT8208A/B Programmable Output V oltage Single Synchronous Buck Controller General D escription The RT8208A/B is a con stant-on-time PWM controller which provide s f our re sistor programmable DC output voltages by controlling the G0 and G1 digital input. The output voltage is programmable from 0.75V to 3.3V. The RT8208A/B offers the lowest total solution cost in systems where need output voltage slewing. The RT8208A/B provides an automatic ma sking power good output during output voltage transition. The constant-on-time PWM control sche me handles wide input/output ratios with ea se and provides 100ns “ instanton” respon se to loa d tra nsient while maintaining a relatively constant frequency.
