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 modulations (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-board power-up sequencing, the power-good outputs, internal soft-start, and internal soft-discharge output that prevents negative voltages on shutdown
