The IC integrates three fixed frequency pulse-width-modulation (PWM) controllers and two linear regulators along with monitoring and protection circuitry into a single 24 lead SSOP package. The two PWM controllers that regulate the system main 5V and 3.3V voltages are implemented with synchronousrectified buck converters.
