Working Principle

The PG02S4803A is a digitally controlled, step-down, DC-DC converter with a wide range of adjustable voltage and current outputs. It consists of a switching stage and an output stage. The switching stage includes an internal high-side/low-side power transistor, inductor, bypass capacitors, and control circuit. The output stage includes an error amplifier, a feed-forward compensation circuit, output capacitor, current sense amplifier, and a PWM dimming switch.

In the switching stage, the high-side/low-side power transistors convert the input voltage levels into step-down voltage levels. The output of the switching stage is filtered by an inductor and bypass capacitors to create a smoother output voltage. The output stage modifies the converted voltage to match the desired voltage and current levels. The output is amplified by an error amplifier, feed-forward compensation circuit, and output capacitor. The current sense amplifier monitors the output current level. The PWM dimming switch is connected to a PWM signal to enable and disable the output.

The PG02S4803A DC/DC converter is a reliable and efficient device for a wide range of applications including industrial automation, medical equipment, and renewable energy systems. It features low voltage step-down conversion with built-in synchronous Rectifier or Boost Switch, and Active Clamp topology. Moreover, it has built-in GOV/DCFOV to program the output voltage. The converter also supports I2C and SMBus digital protocols along with power good signal and output short-circuit protection.
