The EVQ70240FS-RH-00A is an evaluation board designed to demonstrate the capabilities of the MPQ70240FS-AEC1, a power management solution that integrates three high-efficiency step-down DC/DC converters and a low-noise, low-dropout (LDO) regulator.

The MPQ70240FS-AEC1 uses a unique, dual-stage, 18V buck architecture that maximizes efficiency for the 1.8V image sensor I/O rail in the complementary metal oxide semiconductor (CMOS) sensor in high-resolution camera modules.

Constant-on-time (COT) control with phase-locked loop (PLL) provides a fast transient response time for the MPQ70240FS-AEC1. The MPQ70240FS-AEC1 supports a 2.2MHz fixed switching frequency (f_SW).

The MPQ70240FS-AEC1 supports a PMBus interface for application flexibility. In addition, fault statuses can be monitored. Fault protections include input under-voltage lockout (UVLO), over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and thermal shutdown. The one-time programmable (OTP) memory is provided to preset these functions.

The MPQ70240FS-AEC1 supports applications with a high automotive safety integrity level up to ASIL-B. Functional safety features include analog built-in self-testing (ABIST), diagnostics, and a power good (PG) output pin. The MPQ70240FS-AEC1 is developed under MPS's advanced MPSafe^TM functional safety product development process, which has been independently certified to meet ISO 26262 guidelines.

The EVQ70240FS-RH-00A is a fully assembled and tested evaluation board. The MPQ70240FS-AEC1 is available in a QFN-15 (2.5mmx3.5mm) package with wettable flanks. It is available in AEC-Q100 Grade 1.
