DESCRIPTION
The L6610 is a control and housekeeping IC developed in BCD technology; it is intended for acting at the secondary side of desktop PCs or servers switching power supplies, in presence of standard voltage rails (+3.3V, ±5V, ±12V) generated by a main converter and of a supply line generated by an auxiliary converter. The typical application circuit is showed on the front page.
