General Description
The LD5761 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.
With complete protections in it, like OLP (Over Load Protection), OVP (Over
Voltage Protection), fast OSC...
