Power device for switching power supplies realizing high-efficiency New three terminal IPD series for energy-saving standby power supply

OverviewThis IPD series realizes the low noise by higher-efficiency than existing 3 terminals MIP3EX series by world wide input and newlyadded frequency jitter function. This IC is suitable for 60W class power supply.

Feature• Reducing the average noise

Adding a frequency jitter function to MIP2E/3E* series to dramatically reduce the average noise and simplify EMI parts

• Stabilization of maximum electric power by input correctionCorrecting the input voltage dependency of I LIMIT reduces the input voltage dependency of maximum output current

• Overheating protection functionChanged from stopping in latch mode to self reset type

• Protecting functionOverload protection, overheat protection

ApplicationsFlat-screen television, audio and others
