Product Description
STMicroelectronics VIPER12ASTR-E is an advanced high-voltage offline PWM controller integrating a fixed frequency PWM controller and a 700V vertical power MOSFET within an 8-pin SOIC surface mount package. It operates at a switching frequency of 60 kHz and supports a maximum supply voltage of 50V, making it suitable for reliable power conversion and management tasks.
The device features a low start-up supply current of 1mA and a typical operating supply current of 5mA, ensuring efficient power management with minimal losses. Its output voltage capability reaches up to 730V, delivering an output current of 480mA to power loads effectively. The PWM controller uses current mode control technology with a limited maximum duty cycle of 16%, providing precise output regulation and protection.
Designed for rugged industrial use, this PWM controller functions reliably over a wide operating temperature range from -40°C to 150°C. The compact SOIC package with dimensions of 5 mm length, 4 mm width, and 1.65 mm height facilitates easy PCB placement and space-saving designs. Compliance with JESD97 and ECOPACK standards assures environmental friendliness and operational robustness.
