The 78ST235HC is a Grade-C Multi-Channel, High-Voltage, Voltage Regulator within the family of DC-DC Switching Regulators. This type of voltage regulator is primarily used for switching power supplies. The 78ST235HC is a three voltage regulator that provides a regulated output voltage across three channels. It is used in many applications that require high-voltage and high power supplies.

The 78ST235HC is designed to work with a wide variety of input and output configurations. The input voltage range is from 36V to 150V, with output voltage ranges from 24 to 50V. The 78ST235HC is also capable of providing up to 500mA continuous power output and a peak power of up to 1.5A. It has built in thermal protection, over-voltage protection, over-current protection, as well as short-circuit protection, making it a reliable and robust voltage regulator.

The 78ST235HC is an adjustable DC-DC switching regulator with a wide range of features. It has an adjustable current limit and an adjustable output voltage. Additionally, it has an enable pin that allows the regulator to be remotely enabled and disabled. The 78ST235HC also features soft-start and over-temperature shut-off protection.

The 78ST235HC is an ideal choice for applications requiring an efficient and low noise voltage regulator. It is also suitable for applications with power requirements that exceed traditional linear-regulator performance. In addition to its efficiency and low noise levels, the 78ST235HC provides a wide range of voltage control and protections.

The working principle of the 78ST235HC Voltage Regulator is based on a switch mode power supply (SMPS). In a SMPS, DC is converted to a higher voltage using a switching transistor and a transformer, then rectified and regulated to the desired output. This conversion is done at a high frequency, allowing for greater efficiency than linear regulators. The 78ST235HC is a buck topology voltage regulator, meaning it will lower the input voltage to the desired output voltage.

The 78ST235HC is designed to operate in either frequency mode or voltage mode. In frequency mode, the switching frequency is set manually and the voltage is sensed continually. The 78ST235HC starts in frequency mode then switches to voltage mode when the output voltage is correctly adjusted. In voltage mode, the output voltage is regulated directly. The switch transitions occur every time the voltage reaches the desired output voltage. This ensures the output voltage is stabilized across any load or line conditions, providing a clean and stable voltage.

The 78ST235HC is widely used in industrial, automotive, telecom, audio, and computer systems. It can be used to regulate a wide range of AC and DC voltages for a variety of applications. It is an ideal choice for powering high power applications like motor control systems, audio amplifiers, and power supplies. Additionally, the 78ST235HC is used in high voltage solar and power storage systems.

In conclusion, the 78ST235HC is a high-voltage, multi-channel voltage regulator that is suitable for a huge range of applications. It has built in protections making it reliable and robust. It is capable of providing a regulated output with high efficiency and low-noise levels. Moreover, it features a wide range of voltage control and protections, making it an ideal choice for a variety of applications.
