The RT8205L/M is a dual step-down, switch mode power supply controller generating logic-supply voltages in battery powered systems.

It includes two Pulse-Width Modulation (PWM) controllers adjustable from 2V to 5.5V, and also

fixed 5V/3.3V linear regulators. Each linear regulator provides up to 100mA output current with automatic linear regulator bootstrapping to the PWM outputs. An optional external charge pump can be monitored through SECFB (RT8205M). The RT8205L/M includes on-board power up sequencing, a power good output, internal soft-start, and internal soft-discharge output that prevents negative voltage during shutdown. The constant on-time PWM control scheme operates without sense resistors and provides 100n.
