NXP Semiconductors FS23 SBC PMIC Evaluation Boards enable the evaluation, design, implementation, and validation of FS23x fail-safe, body/comfort System Basis Chips (SBCs). The KITFS23LDOEVM and KITFS23SKTEVM boards are soldered boards supporting the FS2300 fail-safe SBCs. KITFS23LDOEVM offers three low dropout (LDO) regulators, while the KITFS23SKTEVM board provides three LDOs and an FS2320 fail-safe SBC with one SMPS and two LDOs. The KITFS23BUKEVM board is a soldered board supporting the FS2320 fail-safe SBCs with one SMPS and two LDO regulators. Devices can be placed and removed easily from the boards using a socket. KITFS23LDOEVM and KITFS23BUKEVM include a soldered FS2320 device with empty OTP content, allowing users to burn the OTP configuration.
