iW1699B Datasheet | Dialog Semiconductor

Off-Line Digital Green-Mode Quasi-Resonant PWM Controller 1 Description The iW1699B is a high performance AC/DC power supply controller that uses digital control technology to build peak current mode PWM flyback power supplies. The device operates in quasi-resonant mode to provide high efficiency along with a number of key built-in protection Features while minimizing the external ponent count, simplifying EMI design and lowering the total bill of material cost. The iW1699B removes the need for secondary feedback circuit while achieving excellent line and load regulation. It also eliminates the need for loop pensation ponents while maintaining stability over all...
