Feeling Technology FP5462
The FP5462 is a single chip composed of a 2.5V precision voltage reference regulator, totem-pole output stages, two pulse width modulation control circuits each with one error amplifier and one duty comparator (DTC). Its built-in functions includes under-voltage lockout circuit (UVLO) and short circuit protection circuit (SCP). With above features, it offers space and low cost solutions in many applications such as the DC / DC converter.GENERAL DESCRIPTION
