S-8356Q28MC-OYNT2U

The S-8356Q28MC-OYNT2U is a dc dc switching controller from the Power Management Integrated Circuit (PMIC) Voltage Regulators product family by Renesas Electronics. The device has various functions such as over current protection, switch current limitation and fault detection allowing customers to develop power supplies that satisfy safety and performance requirements needed in a wide range of applications. Its over current protection function is designed to protect the system from over current or short circuit by quickly detecting the over current condition of a field effect transistor (FET) within the regulator, and turning the FET off before it consistently supplies excessive current. With the protection function in place, the device is suitable for developing various dc dc converters, namely buck and boost converters, used in fields such as those requiring high output current and those using a multi-output of 5 V supply. The S-8356Q28MC-OYNT2U is a type of high side device that can control the FET by providing a PWM signal with an on-off ratio. It can accurately sample the input and output voltages of the circuit and control the FET accordingly. The PWM switching frequency and duty cycle can be set in order to control the current output of the circuit, making it well suited for applications requiring high output voltage accuracy or low output voltage ripple.Apart from the protection and PWM functions, the S-8356Q28MC-OYNT2U also offers other features such as a Soft-start function and an Overvoltage protection (OVP) circuit to prevent overvoltage from occurring on the output side. The Soft-start function adjusts the output voltage gradually during the start-up period, supplying power to the system more automatically and safely. The OVP circuit provides a warning when an overvoltage occurs on the output side and stops the supply before the specified output voltage is exceeded, ensuring safe operation.The S-8356Q28MC-OYNT2U device also offers a Fault detection (FD) circuit to detect any failure of the FET or circuit, such as a short circuit or overcurrent condition. The FD circuit can detect the fault and stop the FET’s operation, immediately cutting off the output current, and protecting the system from damage.In terms of its flexibility, the S-8356Q28MC-OYNT2U also offers a variety of output voltage setting and control options. Output voltage setting can be adjusted by using an external resistor in order to accommodate various system requirements, while the FET on-off control timing can be set through the PWM pin. The device also offers built-in synchronization functions, allowing output voltage to be adjusted with the PWM frequency. Overall, the S-8356Q28MC-OYNT2U is a highly versatile the dc dc switching controller from Renesas\' PMIC Voltage Regulators product family. With its protection and control features, such as over current protection, switch current limitation and fault detection, it is suitable for applications requiring high output voltage accuracy and low output voltage ripple as well as systems requiring a multi-output of 5 V supply.
