i W1782 Rapid Charge™ AC/DC Digital Quasi-Resonant PWM Controller 1 Description The i W1782 is a high performance AC/DC power supply controller for rapid charge that uses digital control technology to build peak-current mode PWM flyback power supplies. The device operates in quasi-resonant mode to provide high efficiency and a number of key built-in protection Features . The i W1782 can achieve tight multi-level constant voltage and multi-level constant current regulation without a traditional secondary-feedback circuit. It also eliminates the need for loop pensation ponents while maintaining stability over all operating conditions. The i W1782 is optimized to work with Dialog’s i W636 secondary-side controller for Qualm® Quick Charge™ 3.0 (QC3.0) technology, to achieve fast and smooth voltage transition upon request by mobile devices (MD). When paired with the i W636, the i W1782 eliminates the discrete decoders on the primary side, minimizes the external ponent count...
