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 frequenc...
