iW1770 operation equivalent, off-line digital quasi-resonant pwm controller with peak power operation.
while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. The iW1770 can operate at peak power mode with momenta.
The iW1770 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 includes a number of .
