FP5453
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.
Features
Wide Operating Voltage Range: 3.
