Overview
iW1677 Low-Power Off-Line Digital Green-Mode PWM Controller 1 Description 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 fast start-up without compromising no-load power loss.
The device directly drives a power BJT and operates in quasi-resonant mode to provide high efficiency along with a number of key built-in protection features while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost.
The iW1677 removes the need for secondary feed...
