LD5761B 04/27/2015 High Voltage with Two-Level Frequency REV: 00 Green-Mode PWM Controller General Description The LD5761B is a Green Mode PWM IC which is built-in with brown-in/out functions in a SOP-7/SOP-8 package. The device could minimize the component counts, circuit space, and reduces the overall material cost of power applications. The two-level frequency of operation enables excellent performance and high efficiency at nominal line. While in low line, just operate in high-level frequency to reduce BMAX. Without changing transformer design, the energy loss is perfectly minimized.
