EVQ7920-R-00A

EVQ7920-R-00A is an evaluation board designed to demonstrate the capabilities of the MPQ7920, a power management IC (PMIC) solution with four integrated, high-efficiency, DC/DC step-down converters, five low-dropout (LDO) regulators, and a flexible industry-standard synchronous serial interface. Constant-on-time (COT) control provides fast transient response for the step-down converters. During continuous conduction mode (CCM), the adjustable switching frequency (fSW) (up to 2.75MHz) reduces the external inductance and capacitance. The output voltage (VOUT) can be adjusted via the industry-standard synchronous serial interface, or can be preset by the memory. The start-up and shutdown sequences can be configured via the memory or the industry-standard synchronous serial interface. Full protection features include under-voltage lockout (UVLO) protection, over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown.
