Dual PWM Controller with Short Circuit Restart Function
General Description
The FP5453 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
duty comparator (DTC). Its built-in functions includes under-voltage lockout circuit (UVLO) and
programmable auto-restart timer for short circuit protection (SCSAR). With above features, it offers
space and low cost solutions in many applications such as the DC / DC converter.
FP5453, 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.

Voltage Reference
FP5453 includes an internal 2.5V reference regulator to provide its internal circuits’ voltage bias.
It also can be used with external resistive divider which connecting to the IC error amplifier inverting
input to provide output feedback reference (see Fig 14).
