The S-85S1AB11-I6T1U switching regulator is a device used in the Power Management Integrated Circuit (PMIC) field to regulate battery voltage and maintain it over a preset range. It belongs to the Voltage Regulator – DC DC Switching Regulator family. A DC DC switching regulator is an integrated circuit that obtains energy from a DC power source, converts it into a DC output voltage and maintains the output voltage at a specified level. It helps in providing a constant voltage output for a range of input voltage supply. Switched mode power supplies have various advantages over linear regulators, such as multiple output voltages, higher efficiency and lower costs. They are used in consumer electronics and other applications where the demanded power fluctuates.

The S-85S1AB11-I6T1U regulator uses a built-in active-clamp reset which prevents voltage overshoots during the ultrafast transient response. The device is also suitable for high frequency synchronization, since it offers a margin of frequency that ranges from 200kHz to 2.5MHz. The S-85S1AB11-I6T1U is capable of producing a constant 5V output voltage, with an input voltage of up to 12V. The device has a current level of 1A and features a typical power efficiency of 84%.

The S-85S1AB11-I6T1U device works on the principle of pulse width modulation (PWM). In the case of PWM, the voltage is regulated by varying the width of the output pulses. The voltage is modulated by switching the load between two states; either the load is disconnected, or connected. In the case of the S-85S1AB11-I6T1U, the load is driven in an unregulated, variable voltage mode. To adjust the output voltage, a combination of a fold-back drive and continuous conduction is used. A pulse-width-modulated signal is generated by the combination of two components. One is an on-time signal, which controls how long the load is connected, and the other is an off-time signal, which controls how long the load is disconnected.

The S-85S1AB11-I6T1U device is versatile, as it supports multiple applications like automotive, medical, telecommunications and HVAC systems. It is also suitable for high frequency synchronization, since it offers a wide range of frequency from 200kHz to 2.5MHz. As the S-85S1AB11-I6T1U regulator is lightweight, it is typically used for power systems that are space or weight constrained. With its low power consumption, it helps reduce the overall power consumption of a system thus improving its efficiency.

The S-85S1AB11-I6T1U switching regulator is a high efficiency, versatile device suited for power management applications. Its ability to regulate a wide range of input voltage makes it suitable for various applications. The device has built-in features like pulse width modulation, fold-back and continuous conduction, making it ideal for use in high speed synchronization. Its high efficiency and low power consumption make it a great choice for systems that require low electrical noise. In addition, its high frequency range and compact size make it a great choice for space and weight sensitive applications.
