iW1816 - Off-Line Digital Green-Mode PWM Controller

General Description

The iW1816 is a high performance AC/DC power supply control device which uses digital control technology to build peak current mode PWM flyback power supplies.

Key Features

  • while minimizing the external component count, simplifying EMI design, and lowering the total bill of material cost. The iW1816 removes the need for secondary feedback circuit while achieving excellent line and load regulation. It also eliminates the need for loop compensation components 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 respons.
