IW1677 controller equivalent, low-power 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 iW1677 removes the need for secondary feedback cir.
The iW1677 is a high performance AC/DC power supply controller which uses digital control technology to build peak current mode PWM flyback power supplies. The device together with an external active device (depletion mode NFET or NPN BJT) provides a.
