The S-85S1PD37-I8T1U voltage regulator is a DC-DC switching regulator of the PMIC – Voltage Regulators family. The device is widely used in automotive, industrial, computing and communication equipment applications, as well as in many other applications where high efficiency and robust power delivery are needed.

The S-85S1PD37-I8T1U is a high efficiency DC-DC buck regulator specifically designed to drive loads up to 10A. It is capable of delivering the power with robustness, tight tolerance and high efficiency. The switching reguator provides the system designers an easy-to-use solution with a PWM (pulse width modulation) control scheme. The PWM controller supports a wide range of load current, from minimum to more than 10A, with very low EMI oscillation.

The S-85S1PD37-I8T1U features a high efficiency power conversion circuit that is capable of operating with very low losses. The device can generate a steady output voltage from a single input voltage source (such as the battery) and is fully protected against any current or voltage over-suply and short-circuit conditions. The IC controller also provides many safety features such as over-temperature and under-voltage protection.

The S-85S1PD37-I8T1U also features an integrated enabler interface. This interface can be used to control the regulator’s output voltage. The enabler includes a digital interface (DSPI, I2C, and UART protocols) or a stand-alone hardwired system. The enabler also includes integrated linear and non-linear control feedback loops that provide precise voltage regulation.

The integrated feedback control circuitry of the enabler helps to maintain precise voltage regulation even under varying load conditions. The linear feedback loop controls the output voltage according to the load, while the non-linear feedback loop is used to compensate for the effects of changing temperatures on the output voltage. The integrated feedback control circuitry also provides an overload shutdown circuit that will shut down the device if the output voltage exceeds the specified threshold.

To ensure high efficiency operation, the S-85S1PD37-I8T1U uses a synchronous rectifier architecture. This modulator uses a peak current sensing architecture that allows very tight duty cycle regulation. The integrated switching frequency is adjustable from 500 kHz to 1.6 MHz, providing a wide range of control for the designers. An integrated PWN (pulse width modulation) controller is also used to provide a precise control of the output voltage.

The integrated switching MOSFET drivers of the S-85S1PD37-I8T1U are capable of providing high-side and low-side current-sensing capabilities and provide a broad range of protection against any fault condition. The device also includes a package of robust over-voltage, over-current and thermal protection features.

Overall, the S-85S1PD37-I8T1U is an excellent choice for any design that needs a high performance, reliable and efficient DC-DC converter. The device is capable of operating from a wide range of input voltages, supports a wide range of output voltages and provides high efficiency operation at a very low component count.
