2011-04-18 Add precise output adjustment to low-voltage supplies
To tweak supply-voltage levels and adjust voltage margins as required, the circuit introduces an op amp and digital potentiometer to control the feedback voltage to the voltage regulator.
2010-12-02 Identify settling time for wideband amp
Read this article to learn how to measure settling time. It is the elapsed time from input application until the output arrives at and remains within a specified error band around the final value.
2010-11-16 Automotive LED driver IC packs core functionality
NXP delivers LED driver IC solutions which incorporate critical functionality such as direct LED temperature feedback, LED fault detection, internal PWM control for dimming and short circuit protection.
