The CXSD62111 offers a compact power supply solution to provide 2 voltages required by notebook application. The 2 PWM controllers use current-mode scheme with phase shift 180 degrees control scheme allow to use MLCC output capacitors. The higher fixed 1MHz switching frequency allows to use thin and small filtered components. The CXSD62111 provides good transient response and accurate DC output voltage in either PSM or PWM Mode. In Pulse Skipping Modulation Mode (PSM), the CXSD62111 provides high efficiency over light to heavy loads with loading modulated switching frequencies. The unique ultrasonic mode maintains the switching frequency above 25kHz, which eliminates noise in audio applications. The CXSD62111 built in individual enable control input on 2 channels for flexible power sequence adjustment. The powergood outputs (SYSPOK) indicate the operating mode of the PWMx. The ACXSD62111has been equipped with excellent protection functions: Power-on-RESET (POR), over-current protection (OCP), over-voltage protection OVP, under-voltage protection (UVP) and over-temperature protection (OTP) to prevent the device operate under abnormal condition or adjacent pin shortage
