STMicroelectronics, Inc. DC/DC & AC/DC (Off-Line) SMPS Evaluation Boards STEVAL-ISA046V2

The STMicroelectronics evaluation board, part number 09R5918, is designed for synchronous buck conversion applications. It operates within an input voltage range of 2.7 V to 5.5 V and provides a fixed output voltage of 3.3 V with a maximum output current of 2 A. The board features a high internal switching frequency of 1.5 MHz, allowing for the use of compact surface-mount components. Key features include an inhibit function, short-circuit protection, and a current mode PWM topology that ensures low output ripple. The device is housed in a DFN6 3x3 package, making it suitable for low-voltage applications where high efficiency is required to minimize power dissipation and heat generation. This evaluation board is particularly useful for engineers looking to replace high current linear solutions in their designs.
