MP5479 - 2.7V to 5.5V PMIC

General Description

The MP5479 is a complete power management solution that integrates four high-efficiency stepdown 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.

Key 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) interface. The power-on/off sequence is also programmable via the MTP and can be controlled through I2C bus online. The MP5479 requires a minimal number of external components, and is available in a space-saving QFN-26 (3.5mmx4.5mm) package with wettable flanks.

MP5479 2.7V to 5.5V PMIC with Four 2A/2.5A/4.5A/4.5A Buck Converters, 5 LDOs, and Configurable System Settings via I2C and MTP DESCRIPTION The MP5479 is a complete power management solution that integrates four high-efficiency stepdown 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 the 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) interface.
