UTP28SP90 is a high voltage silicon power module developed by United Territory Power (UTP). It is designed for high voltage applications, up to 1000V, with a dielectric strength of 2800V. The high power density makes it suitable for applications including electric vehicle power supplies, wind turbine power systems, high efficiency AC/DC power distribution, and off-grid operations.

UTP28SP90 is a monolithic, surface mount package that utilizes the direct copper bonding (DCB) of the metal base material to the semiconductor substrates for improved electrical performance. The low thermal resistance of the metal base material feature enhances device lifetime without the need for external cooling. It has a low profile with enhanced solder joint robustness and vibration resistance.

The UTP28SP90 has excellent electrical characteristics. It features a fast reverse-recovery time, which enables fast turn-on and turn-off of loads. Its low forward voltage drop of 0.2V helps reduce losses, while its low output capacitance helps reduce system noise. Its high peak current capability provides maximum power output for various loads. The UTP28SP90 also features an integrated temperature sensor and current limit protection to ensure safe operation.

The working principle of the UTP28SP90 is based on the switching of the circuit from flyback mode to buck-boost mode while switching the load. The UTP28SP90 utilizes a built-in high-frequency off-line converter, capable of providing power to multiple loads simultaneously with variable output voltage. The output voltage can be adjusted with a voltage set point or a potentiometer. The load current is monitored and limited with an internal current-limit circuit, which prevents overloading the power supply or the loads.

The UTP28SP90 is suitable for a wide range of applications such as LED lighting, renewable energy systems, industrial automation, telecom and computer power supplies, power supply modules, AC-DC converters, motor control, and HVAC control systems. It has a wide operating temperature range of -40C to +85C and is capable of handling a high surge current of up to 40A. It is also RoHS compliant.

In summary, UTP28SP90 is a high voltage silicon power module designed for high voltage applications with excellent electrical characteristics. It provides efficient power in devices requiring fast turn-on and turn-off of loads. Through its low forward voltage drop and integrated temperature sensor, the module ensures safe operation while increasing system efficiency. Furthermore, the UTP28SP90 is suitable for a wide range of applications due to its wide operating temperature range and RoHS compliance.
