MP5496 - Power Management

Description

The MP5496 is a complete 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.

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.

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 OTP DESCRIPTION The MP5496 is a complete 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. Full protection features include undervoltage lockout (UVLO), over-current protection (OCP), and thermal shutdown.
