The RT8205A/B/C dual step-down, switch-mode powersupply controller generates logic-supply voltages in battery-powered systems.

2 linear regulators providing fixed 5V and 3.3V outputs. The linear regulator each provides up to 70mA output current with automatic linear-regulator bootstrapping to the PWM outputs. The RT8205A/B/C includes on-board power-up sequencing, the power-good output, internal softstart, and internal soft-discharge output that prevents negative voltages on shutdown. A constant on-time PWM control scheme operates without sense resistor and provides 100ns response to load transients while maintaining a r.
