EVQ7928-RH-00A MPSafeTM-Compatible, 18V, 4-Channel PMIC with 3 Bucks and 1 LDO Evaluation Board, AEC-Q100 Qualified
The EVQ7928-RH-00A is an evaluation board designed to demonstrate the capabilities of the MPQ7928-AEC1, a power management solution that integrates three high-efficiency, step-down DC/DC converters and a low-noise, low-dropout (LDO) regulator.
The MPQ7928-AEC1’s unique, dual-stage, 18V buck architecture maximizes efficiency for the 1.8V image sensor input/output (I/O) rail in the complementary metal-oxide-semiconductor (CMOS) sensor found in high-resolution camera modules. Constant-on-time (COT) control with phase-locked loop (PLL) provides a fast transient response time for the MPQ7928-AEC1. The 2.2MHz fixed switching frequency (fSW) during continuous conduction mode (CCM) greatly reduces the size of external inductors and capacitors.
The MPQ7928-AEC1’s configurable parameters are set via the I2C digital interface without requiring any additional hardware changes, which allows for application flexibility. The output voltage (VOUT), power sequence, and protection thresholds can all be adjusted through the interface.
Fault statuses can also be monitored. Protection features include input under-voltage lockout (UVLO), over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and thermal shutdown (TSD). The built-in power good (PG) indicator determines whether the MPQ7928-AEC1 operates properly.
The EVQ7928-RH-00A is a fully assembled and tested evaluation board. The MPQ7928-AEC1 is available in a QFN-15 (2.5mmx3.5mm) package with wettable flanks, and it is available in AEC-Q100 Grade 1.
