MP5479 Datasheet 2.7v To 5.5v Pmic

Manufacturer: Monolithic Power Systems

Overview: 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.

General Description

The MP5479 is a plete 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.

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.
