RT8208E/F Programmable Output Voltage Single Synchronous Buck Controller General Description The RT8208E/F is a constant-on-time PWM controller which provides four resistor programmable DC output voltages by controlling the G0 and G1 digital input. The output voltage is programmable from 0.75V to 3.3V. The RT8208E/F offers the lowest total solution cost in systems where need output voltage slewing. The RT8208E/F provides an automatic masking power good output during output voltage transition. The constant-on-time PWM control scheme handles wide input/output ratios with ease and provides 100ns “instanton” response to load transient while maintaining a relatively constant frequency.
