MP5496GR-0001 Datasheet Power Management

Manufacturer: Monolithic Power Systems

Overview: MP5496 2.8V to 5.5V, Power Management IC with Four 4.5A/2.5A/4A/2A Buck Converters, 5 LDOs, and Flexible System Settings via I2C and.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MP5496 is a plete power management solution that integrates four high-efficiency, stepdown DC/DC converters, five low-dropout (LDO) regulators, and a flexible logic interface.

A DC/DC converter with constant-on-time (COT) control provides fast transient response.

The default 1.5MHz fixed switching frequency during continuous conduction mode (CCM) greatly reduces the external inductor and capacitor values.

Key Features

  • include undervoltage lockout (UVLO), over-current protection (OCP), and thermal shutdown. The output voltage is adjustable through the I2C interface, or can be preset by the one-time programmable (OTP) function. The start-up and shutdown sequences can be configured via the OTP. By using the I2C or OTP, the MP5496 can be utilized to configure the buck and LDO output voltages, mode, buck 1 and buck 3 current limits, and the enable function of all the buck converters and LDOs (ENBUCK/LDO). When usi.
