Monolithic Power Systems MPQ7920 | Demoboard EVQ7920-R-00A

Beschreibung

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 I2C 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.
