Description: ® RT8230A/B/C/D/E Dual-Channel Synchro nous DC/DC Step-Down Controller with 5V /3.3V LDOs General Description The RT8 230A/B/C/D/E is a dual-channel step-dow n, controller generating supply voltage s for battery-powered systems. It inclu des two Pulse-Width Modulation (PWM) co ntrollers adjustable from 2V to 5.5V, a nd two fixed 5V/ 3.3V linear regulators . Each linear regulator provides up to 100mA output current. The 5V linear reg ulator supplies power to the PWM driver s. The RT8230A/B/C/D/E includes on-boar d power-up sequencing, a power-good out put, internal soft-start, and soft-disc harge output that prevents negative vol tage during shutdown. A constant curren t ripple PWM control scheme operates
