Application Field

The S6BP201A7AST2B000 is well suited for automotive applications where a high efficiency DC-DC converter is needed. It can be used in a variety of applications such as DC-DC converters for headlight and interior lighting control, automobile power supply systems, automotive communication systems and automotive entertainment systems. It can also be used in other applications such as medical, industrial and telecom power supplies.

Working Principle

The S6BP201A7AST2B000 uses a synchronous buck converter topology, which is an efficient and reliable way to deliver power from a DC source. The device is designed to efficiently convert a higher input voltage to a lower output voltage. The regulator uses a voltage feedback loop to maintain the preset output voltage. The output stage of the regulator consists of a P-channel MOSFET as the high side switch and an N-channel MOSFET as the low side switch.

In the case of an overcurrent situation, the device will automatically shut off the output and go into a latched off condition. To reset the regulator, a reset signal must be applied to the output enable pin. The reset signal can be provided by a system controller or by manually cycling the power supply.

The S6BP201A7AST2B000 also has protection against overvoltage as well as short circuit protection. If the input voltage exceeds the set maximum input voltage, the device will shut off the output and go into an overvoltage protection mode. If the output is short circuited, the device will also shut off the output and go into a short circuit protection mode.

The S6BP201A7AST2B000 is equipped with active rectification, which improves efficiency by eliminating the need for external rectifier diodes. This helps to reduce component count and the overall power losses of the converter, which leads to improved system efficiency.

Conclusion

The S6BP201A7AST2B000 is an automotive grade DC-DC switching regulator based on a synchronous buck converter topology. It is designed for applications operating from a 9V to 17V input voltage range, with up to 10A of output current and between 0.5V to 12V of output voltage. The device features a variety of features that make it suitable for a wide range of automotive applications, including adjustable output voltage, overcurrent protection, input voltage monitoring, output current monitoring, overvoltage protection and active rectification.
