iW1691 controller equivalent, digital pwm current-mode controller.
*
* Primary-side feedback eliminates opto-isolators and simplifies design
*
* Quasi-resonant operation for highest overall efficiency
*
* EZ-EMI ® de.
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.
