MAX8649A - 1.8A Step-Down Regulator

Download the MAX8649A datasheet PDF. This datasheet also covers the MAX8649 variant, as both devices belong to the same 1.8a step-down regulator family and are provided as variant models within a single manufacturer datasheet.

Description

The MAX8649/MAX8649A high-efficiency DC-to-DC stepdown switching regulators deliver up to 1.8A of output current.

The device operates from a 2.5V to 5.5V input voltage range, making it future proof for next-generation battery technologies.

The output voltage is I2C programmable from 0.75V to 1.38V.

Features

  • include internal soft-start control circuitry to reduce inrush current, output overvoltage, overcurrent, and overtemperature protection. The ICs feature different I2C addresses so that devices may be used in a system. For a 2.5A version of this device, refer to the MAX8952 data sheet.

19-4504; Rev 4; 6/11 EVAALVUAAILTAIOBNLEKIT 1.8A Step-Down Regulator with Remote Sense in 2mm x 2mm WLP MAX8649/MAX8649A General Description The MAX8649/MAX8649A high-efficiency DC-to-DC stepdown switching regulators deliver up to 1.8A of output current. The device operates from a 2.5V to 5.5V input voltage range, making it future proof for next-generation battery technologies. The output voltage is I2C programmable from 0.75V to 1.38V. Remote sense ensures precise DC regulation at the load. Total output error is less than 2% over load, line, and temperature. The ICs operate at a 3.25MHz fixed frequency. The high operating frequency minimizes the size of external components. The switching frequency of the converter can be synchronized to the master clock of the application.
