IW1812 controller equivalent, off-line digital green-mode pwm controller.
while minimizing the external component count, simplifying EMI design, and lowering the total bill of material cost. The iW1812 removes the need for secondary feedback ci.
The iW1812 is a high performance AC/DC power supply control device which uses digital control technology to build peak current mode PWM flyback power supplies. This device includes an internal power BJT and operates in quasiresonant mode to provide h.
