New IPD series for chopper power supply
(MIP353/MIP355)

  This is a new product with higher functionality comparing to existing MIP28X/MIP38X series. Using external variable terminals enables the over current protection and the oscillating frequency to change at three steps. Adding to an existing over heat protection, overload protecting function and over voltage latch function are built-in. PWM control while normal load and blocking oscillation of low drain peak current while light load enables to reduce the coil sound when light load. Application without photocouplers is also possible.

• Expanding the range of input/output
  The flexibility of designing the power supply is improved by expansion of input/output range with three steps changeover of ILIMIT/oscillating frequency.
• High-efficiency and the reduction of coil sound
  PWM control while normal load and blocking oscillation of low drain peak current while light load enables to reduce the power consumption when light load and achieves high-efficiency at total load field. Especially, lower the drain peak current reduces the coil sound level when light load.
• Lower the average noise
  It is possible to reduce the average noise by frequency jitter function and simplify the EMI parts.
• Protecting function
  Overload protection (timer intermittent), over voltage protection (stopping the latch), overheat protection (self reset)

• IH rice cooker, air conditioners, air purification system, dehumidifier, fan motor (for refrigerators) and washing machines
