MPQ70240FSGRHE-AEC1

The MPQ70240FS-AEC1 is a power management IC (PMIC) solution integrating three high-efficiency step-down DC/DC converters and a low-noise, low-dropout (LDO) regulator. Its dual-stage, 18V buck architecture 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 fast transient response. During continuous conduction mode (CCM), the fixed 2.2MHz switching frequency (fSW) greatly reduces external inductor and capacitor sizes. The digital interface allows for application flexibility. The output voltage (VOUT), power sequence, and protection thresholds can all be adjusted via the interface. Fault statuses can also be monitored: 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 such functions. The MPQ70240FS-AEC1 is an ISO 26262 ASIL-B hardware-capable device. 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 MPSafeTM functional safety product development process, which has been independently certified to meet ISO 26262 guidelines. The MPQ70240FS-AEC1 minimizes the external components count, and is available in a space-saving QFN-15 (2.5mmx3.5mm) package with wettable flanks. It is available in AEC-Q100 Grade 1.
