MPQ7920GRM-XXXX-AEC1规格书详情
DESCRIPTION
The MPQ7920 is a complete power management solution that integrates four highefficiency step-down DC/DC converters, five low-dropout regulators, and a flexible logic interface.
Constant-on-time (COT) control in the DC/DC converter provides fast transient response. The adjustable switching frequency (up to 2.75MHz) during CCM greatly reduces external inductor and capacitor value. Full protection features include UVLO, OCP, OVP, and thermal shutdown.
The output voltage is adjustable through the I2C bus or preset by the MTP (multiple-time programmable). The power-on/off sequence is also programmable via the MTP and can be controlled through I2C bus online.
The MPQ7920 requires a minimal number of external components, and is available in a space-saving QFN-26 (3.5mmx4.5mm) package with wettable flanks. This part is AEC-Q100 qualified.
