The FP5452 is a dual channel PWM buck controller with short circuit protection (SCP) and adjustable maximum duty control (DTC) function. It includes one 2.5V precision voltage reference regulator, two error amplifiers, PWM control circuits, totem-pole output stages and the under voltage lockout circuit (UVLO). It offers space and low cost solutions in many applications such as the DC / DC converters and backlight inverters.
Using FP5452, it is easy to complete a power conversion regulator design with few external components. The circuit diagram of the typical application example is as below
