IW1812 Datasheet | Dialog Semiconductor

i W1812 Off-Line Digital Green-Mode PWM Controller Integrated with Power BJT and OTP 1 Description The i W1812 is a high performance AC/DC power supply control device which uses digital control technology to build peak current mode PWM flyback power supplies. This device includes an internal power BJT and operates in quasiresonant mode to provide high efficiency along with a number of key built-in protection Features while minimizing the external ponent count, simplifying EMI design, and lowering the total bill of material cost. The i W1812 removes the need for secondary feedback circuitry while achieving excellent line and load regulation. It also eliminates the need for loop pensation ponents while maintaining stability in all operating conditions. The pulse-by-pulse waveform analysis allows for a loop response that is much faster than traditional solutions, resulting in improved dynamic load response for both one-time and repetitive load transients. The built-in power limit...
