iW1691 controller equivalent, digital pwm controller.
while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. The iW1691 removes the need for secondary feedback cir.
over a wide input voltage range.
The ultra-low operating current at light load ensures that the iW1691 is ideal for appl.
The iW1691 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 operates in quasi-resonant mode at heavy load to provide high efficiency along with.
