4. Power Supply Unit
4-1 Intelligent Power Device (IPD) (Customer Iimitation)
¢ Overview
The IPD employs PWM control*1 by the peak current control method under the rated load and
intermittent oscillation control under light loads, providing high efficiency from light loads to heavy
loads and contributing to low power consumption during standby. *1: MIP004xx provides peak
current control type RCC control (quasi-resonance).

¢ Points on Appeal (Features)
• The MIP2Ex/3Ex series can be used with power sources of up
to 60 W class. By limiting the number of external parts, these
components allow construction of compact, simple power
supplies.
• The MIP2Mx series can be used with power sources of up to 12
W class and incorporates built-in AC input detection functionality.
• The MIP2Fx/2Kx series can be used with power sources of up
to 15 W class. These parts incorporate a built-in ILIMIT input
compensation circuit and reduce the dependency of the maximum
output voltage on the input voltage.
• In addition to dramatically simplifying noise countermeasures through
a combination of quasi-resonance and jitter control, MIP004xx
provides a high level of efficiency from standby through rated load
operation.
