Preliminary RT9212 Dual 5V Synchronous Buck PWM DC-DC and Linear Power Controller General Description The RT9212 is a 3-in-one power controller delivers high efficiency and tight regulation from two voltage regulating synchronous buck PWM DC-DC and one linear power controllers. The RT9212 can control two independent output voltages adjustment in range of 0.8V to 4.0V with 180 degrees channel to channel phase operation to reduce input ripple. In dual power supply application the RT9212 monitors the output voltage of both Channel 1 and Channel 2. An independent PGOOD (power good) signal is asserted for each channel after the soft-start sequence has completed, and the output voltage is within ±15% of the set point.
