Transient Response Posted by: koksalocal on 02/04/2009 How can we increase our power supply transient load response? TOP243GX 20W OPTO-TL431 FEEDBACK UNIVERSAL INPUT OUTPUT 3.3 V 1.5A 评论 Hello koksalocal, In order to improve transient response, you have to two choices. The best way is use a frequency response analyzer, see http://www.venable.biz/ and http://www.venable.biz/tr-papers.php. Another option for people with very limited resources is to use a spice simulation program like LTSpice from http://www.linear.com/designtools/software/ltspice.jsp and implement the model of your power supply. To learn how to use spice tools for power supplies analysis I recommend you Christophe P.
