S-8520B33MC-ARST2G

The S-8520B33MC-ARST2G is a non-insulated, high-side switch control integrated circuit by Samsung Semiconductor. This integrated circuit is designed for the purpose of enhancing power management efficiency in DC to DC converters and switching power supplies. It is commonly used in battery-driven and low noise applications such as air-conditioning systems, medical devices, humidifiers, and PDP TVs.

The S-8520B33MC-ARST2G can drive N-channel MOSFETs with two power inputs. It features an input of 4V - 12V VDD, a supply current of 2.6mA at 12V, an output voltage range of 0V - 12V, an operating temperature of -40°C - 85°C, fast Dynamic Response characteristics, and a low on-resistance of 0.5Ohms max.

The S-8520B33MC-ARST2G is capable of delivering currents up to 30A at a frequency of 5MHz. This integrated circuit also has a low-power mode for power-saving application, as well as an OVP (Over Voltage Protection) function to prevent damage to the device by preventing surge voltages. Additionally, the S-8520B33MC-ARST2G has a temperature protection circuit, a short-circuit protection circuit, and a PWM input compatibility.

The working principle of the S-8520B33MC-ARST2G is that when a voltage is applied to the Enable pin, the internal controllers detect the voltage and compare it to an internally set reference voltage. If the voltage is higher than the reference voltage, the device is activated and the inputs and outputs are connected. If the voltage is lower than the reference voltage, the device is off.

The device works in one of three different modes depending on the level of the Enable pin: Normal mode, Sleep mode and Power-down mode. In Normal mode, the current supplied to the output will always be the same. In Sleep mode, the current is reduced to a small amount, while in Power-down mode the current is reduced to an even smaller amount. The mode is changed by changing the output voltage on the Enable pin.

The S-8520B33MC-ARST2G has many advantages in DC to DC converter applications. It has high switching frequency and high switching power efficiency. It also has a wide range of operating temperature, fast dynamic response, and a low supply current. Most importantly, it can provide voltage and current regulation with high accuracy.
