The new C2172PX8 PSS controller targets low cost, MoU-compliant USB chargers for smartphones, tablets and other universal input applications rated to 7.5 W, whereas the first two C2170 controllers launched in June are optimised for applications to 4 W and 6.5 W.

The new C2172PX8 controller combines the company’s recently patented bipolar transistor (BJT) drive scheme, advanced PSS technology and several power-saving techniques to help manufacturers develop ultra low cost, more energy-efficient BJT-based solutions.  These approaches enable simpler circuits with reduced component counts and system costs but with performance and manufacturing advantages compared with competitive approaches.  CamSemi’s improved drive technology boosts switching performance and delivers higher active mode efficiency, greater product robustness from more Reverse Bias Safe Operating Area (RBSOA) margin and the flexibility to accommodate a wide range of low cost BJTs for further cost savings.

C2172PX8 also offers ‘best in class’ voltage regulation of ±2% and current regulation of ±3% allowing more margin for thermal design; no-load power consumption is well below 30 mW; and IC power consumption and design have been optimised to enable fast start of 500 ms but without needing the extra cost, space and complexity of an active start-up switch.

C2172PX8 is packaged in surface mount SOP8, samples are available now.
