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. The linear controller drives an external transistor to provide an adjustable output voltage.
