Overview
LD7533 9/03/2010 Advanced Green-Mode PWM Controller with Frequency Triple for Peak Power Rev.
00 General Description The LD7533 is an advanced Green Mode PWM controller, which is built-in with frequency triple, multi-protections and EMI-improved solution in a SOT-26/ DIP-8 package.
It’s ideal for applications requiring a cost-effective solution, and minimum component counts and circuit space, especially ideal for high power density and small size product.
The LD7533 is especially designed for switching power supply with peak power.
It incorporates frequency triple function and adjustable OLP timer to handle the peak power with delay time.
The frequency triple function can reduce the transformer flux and core size.
Furthermore, the frequency swapping function is to reduce the noise level and thus helps the power circuit designers for EMI suppression with minimum amount of component cost and developing time.
Features Frequency Triple for peak power (195kHz) Very Low Startup Current (...
