FP5462

FP5462 Dual PWM Controller with SCP/DTC Function General Description 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. Features  Wide Operating Voltage Range: 3.6~40V  Fixed Reference Voltage: 2.5V  Reference Voltage Precision: 1%  Oscillator Frequency: Max. 500KHz  Low Quiescent Supply Current Under 3.5mA  Totem-pole Output Stage  Variable Duty Control (DTC)  UVLO Protection Function  SCP Protection ...
