RT8203 High-Efficiency, Quad Output, M ain Power- Supply Controllers for Notebook Computers General D escription The RT8203 dual step-down, switch-mode power-supply (SMPS) controllers generate logic-supply voltages in battery-powered systems. The RT8203 include two pulsewidth modulation (PWM) controllers, adjustable from 2V to 5.5V or fixed at 5Vand 3.3V . These devices feature two linear regulators providing 5V and 3.3V always-on outputs. Each linear regulator provides up to 100mA output current with automatic linear regulator bootstra pping to the main SMPS outputs. The RT8203 include on-board power-up sequencing, a power-good (PGOOD) output, internal softstart, and soft-shutdown output discharge that prevents negative voltage s on shutdown.
