Product Description

• 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.
