RT8205B - Main Power Supply Controllers

The RT8205A/B/C dual step-down, switch-mode powersupply controller generates logic-supply voltages in battery-powered systems. The RT8205A/B/C includes two pulse-width modulation (PWM) controllers fixed at 5V/ 3.3V or adjustable from 2V to 5.5V. An alternative LGATE1 output LG1_CP can be used for ex.

RT8205B Features

* 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-
