iW1679 Datasheet | Dialog Semiconductor

Description The i W1679 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 directly drives a power BJT and operates in quasi-resonant mode to provide high efficiency and key built-in protection features , while minimizing the external ponent count, simplifying EMI design, and lowering the total bill of material cost. The i W1679 removes the need for a secondary feedback circuit while achieving excellent line and load regulation. It also eliminates the need for loop pensation ponents while maintaining stability over all operating conditions. The pulse-by-pulse waveform analysis allows for fast dynamic load response for both one-time and repetitive load transients. The built-in power limit function enables optimized transformer design for a wide input voltage range. Dialog’s innovative proprietary technology...
