FP5462 Dual PWM Controller with SCP/DTC Function
General Description
Download
 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.
      FP5462, a high performance IC, is designed to complete a control circuit with few external components. The circuit diagram of the typical application example is shown in below.
