STMicroelectronics 15 V 100 mA High Voltage Buck Converter Evaluation Board STEVAL-VP26K01B

STMicroelectronics STEVAL-VP26K01B is a 15 V, 100 mA high voltage Buck Converter evaluation board designed for ultra-wide range auxiliary power supplies requiring input voltages from 60 to 870 VDC or 90 to 600 VAC. This compact evaluation kit features tight line and load regulation to ensure robust performance across varied input voltages and output loads.

The board is based on the VIPER265KDTR device from the VIPerPlus family, incorporating a 1050 V Power MOSFET and PWM current-mode control. It operates at a fixed switching frequency of 60 kHz with frequency jittering, which reduces electromagnetic interference and improves efficiency.

The design eliminates the need for external input voltage limiters or stacked MOSFETs, resulting in a simpler and cost-effective solution with a minimal bill of materials. This makes it suitable for industrial and laboratory use cases where compact size and reliable power conversion are critical.

Typical applications include auxiliary power supplies for power electronics, motor drives, and other power management systems requiring regulated low voltage outputs from a high voltage source. The board supports input frequencies from 50 to 60 Hz, applicable in a wide range of AC mains environments.

The evaluation board supports input voltages from 60 to 870 VDC or 90 to 600 VAC. Output voltage is regulated at 15 V with a maximum output current of 100 mA. Compact size with tight line and load regulation over the entire input and output range.

Utilizes the VIPER265KDTR offline high-voltage converter with 1050 V Power MOSFET and PWM current-mode control. Operates at a fixed switching frequency of 60 kHz with frequency jittering reducing EMI. Low cost solution without input voltage limiter or stacked MOSFETs.
