The 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 (f_SW) (up to 2.75MHz) reduces the external inductance and capacitance.

The output voltage (V_OUT) 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.

The MPQ7920 requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-26 (3.5mmx4.5mm) package with wettable flanks.
