A PWM (Pulse Width Modulation) controller is an electronic device or integrated circuit (IC) that generates a PWM signal to control the power output to a load, such as a motor, LED, or other electrical component. PWM is a modulation technique that involves varying the duty cycle of a square wave signal to control the average voltage delivered to the load.

Description
The BIT3252 is a high frequency PWM controller which integrates the required functions for a boost converter in a small SOP-8 package. A low 0.2V feedback voltage makes the system with high efficiency and its over voltage protection function makes the system reliable. Built-in 55V/1.2A NMOS save the space of PCB and simplify the circuit design. With CMOS process which greatly reduces the operating current, BIT3252A is very suitable for LED backlight application.
