Its voltage regulation accuracy is 0.6%, and it has a maximum power-loss of 1.2W. The S-85S1AB12-I6T1U also supports a wide input voltage range from 4.5V to 20V, and its output voltage is adjustable from 0.9V to 5V. Furthermore, the S-85S1AB12-I6T1U includes comprehensive protection circuits to ensure its safe operation. These features make the S-85S1AB12-I6T1U both cost-effective and reliable.

Working Principle

The S-85S1AB12-I6T1U is a DC-DC switching regulator IC, which means it is capable of taking a direct current (DC) input, modulating it, and outputting an adjustable direct current (DC) output. The product uses a buck topology, meaning it reduces the input voltage, while providing a regulated output voltage. A buck topology is the simplest form of switching regulator.

The S-85S1AB12-I6T1U utilizes an on-board pulse-width modulator (PWM) to regulate its output voltage. The PWM monitors the output voltage and the input voltage, and modulates its duty cycle to maintain a stable output voltage. When the output voltage gradually increases, the duty cycle is reduced, thus reducing the amount of energy transferred from the input to the output. Conversely, when the output voltage decreases, the duty cycle increases, thus increasing the amount of energy transferred from the input to the output.

The S-85S1AB12-I6T1U also uses an external reference pin, which can be used to further fine-tune its output voltage via a resistor divider. This reference pin allows the user to configure the regulator’s output voltage accurately. Once the configuration is set, the S-85S1AB12-I6T1U will maintain the output voltage automatically.

Conclusion

The S-85S1AB12-I6T1U is a highly versatile DC-DC switching regulator that is widely used in multiple embedded systems. It is equipped with numerous protection circuits and can support a wide input voltage range. Furthermore, its sophisticated PWM capability allows for better power efficiency and voltage accuracy. With its flexibility and cost-effectiveness, the S-85S1AB12-I6T1U is an ideal embedded system solution.
