The RT8206A/B dual step-down, Switch Mode Power
Supply (SMPS) controller generates logic supply voltages
in battery powered systems. The RT8206A/B includes
two Pulse Width Modulation (PWM) controllers fixed at
5V/3.3V or adjustable from 2V to 5.5V. An optional external
charge pump can be monitored through SECFB
(RT8206A). This device also features a linear regulator
providing a fixed 5V output. The linear regulator provides
up to 70mA output current with automatic linear regulator
bootstrapping to the BYP input. The RT8206A/B includes
on-board power up sequencing, the power good outputs,
internal soft-start, and internal soft-discharge output that
prevents negative voltages on shutdown
