S-8355L15MC-NCAT2G

The S-8355L15MC-NCAT2G is a DC-DC switching controller. It is a voltage regulator, an integrated circuit (IC) designed to provide a constant output voltage to a system, regardless of its input voltage. The S-8355L15MC-NCAT2G includes an on-chip monitor, error amplifier, voltage reference, a driver stage, and a control logic circuit with protection features. It features a wide input voltage range from 8V to 52V and a high switching frequency (up to 500kHz). It is designed for high-reliability and high-temperature applications.

In terms of application fields, the S-8355L15MC-NCAT2G is suitable for Automotive, Industrial, Military and Aerospace systems that require a wide range of input voltage while providing a secure output voltage. Applications such as telecom power supply systems, UPS systems, data processing, and process automation also benefit from its robust design. It offers high performance, low power consumption, and features various protections that make it a highly reliable and high temperature tolerant device.

The S-8355L15MC-NCAT2G is designed to work as a DC-DC switching controller for two different topologies: Step-down (buck) and Step-up (boost). These two different working principles are based on the different requirements for the input and output. In the Step-down or «Buck» topology, the input voltage must be higher than the output voltage. In this mode, the controller works as a PWM connected to an inductor to reduce the input voltage to the desired output voltage level. On the other hand, the Step-up or «Boost» topology has an input voltage that is lower than the output voltage. In this topology, the controller works as a PWM connected to a transformer, which works as a voltage booster while reducing power loss.

The S-8355L15MC-NCAT2G is a highly reliable and cost-effective device commonly used in power supplies designs. Its wide input and output voltage ranges make it suitable for a variety of system designs and applications. Its high-frequency switching capabilities and the protection features provide enhanced performance and reliability. This makes it an ideal choice for applications that require high-performance, high-reliability, and low power consumption.
