iW1699 controller equivalent, off-line digital green-mode quasi-resonant pwm controller.
while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. The iW1699 removes the need for a secondary feedback c.
a.
The iW1699 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 and key built-in protecti.
