STMicroelectronics SPSA068 | Demoboard STEVAL-SPSA068

Description

The STEVAL-SPSA068 is a tool designed to evaluate SPSA068, a BUCK voltage regulator with a precise voltage reference for automotive MCU applications. All the regulators have internal power switches.An internal programmable memory allows selecting the main device parameters. STEVAL-SPSA068 has been programmed in the following condition: VOUT = 1.2 V, switching frequency = 400 kHz, watchdog disabled, VREF enabled, OV/UV = +/-5%.The SPSA068 is already programmed, so no external microcontroller is necessary to control the STEVAL-SPSA068 application. It is possible to set a VOUT different than 1.2 V by using an external resistor divider.
