产品描述

The EV8843-G-00A is used for demonstrating the performance of MP8843, a highly integrated, high frequency, synchronous, step-down switcher with I2C control interface.

MP8843 supports up to 3A current from a wide input supply range of 2.5V to 6V with excellent load and line regulation. Constant-on-time (COT) control provides fast transient response, high light-load efficiency and easy loop stabilization. The I2C interface allows for communication interface speed up to 3.4Mbps. It controls the output voltage on the fly from 0.6V to 1.1V with 3.9mV voltage steps and it also controls the output voltage transition slew rate. The interface also allows for the selection of power-save mode to meet different application requirements. Protection features include internal soft-start, over-current protection, and over-temperature protection. MP8843 is available in 2mmx2mm 12-pin QFN package.

6V, 3A, Synchronous, Step-Down Switcher With I2C Interface

The MP8843 is a highly integrated, high-frequency, synchronous, step-down switcher with an I2C control interface. The MP8843 can support up to 3A of current from a wide 2.6V-to-6V input supply range with excellent load and line regulation. 

Constant-on-time (COT) control provides a fast transient response, high light-load efficiency, and eases loop stabilization.

The I2C interface allows for communication interface speed up to 3.4Mbps. It controls the output voltage from 0.6V to 1.1V on the fly with 3.9mV voltage steps. This interface also controls the output voltage transition slew rate and allows the power-save mode selection to meet different application requirements. 

Protection features include internal soft start (SS), over-current protection (OCP), and over-temperature protection (OTP).

The MP8843 requires a minimal number of readily available, standard, external components and is available in an ultra-small QFN-12 (2mmx2mm) package.


Configure multiple parameters of the MP88xx including output voltage and fsw.

This I2C GUI allows you to program the MP88xx . By using this I2C GUI, you can set the output voltage, switching frequency, slew rate, and operation mode. Please reference the parts respective user guides for installation and programing instructions.

System Requirements:

Windows 7 or later

.Net Framework 4 or later

6V, 3A, Synchronous, Step-Down Switcher

The MP8843 is a highly integrated, high-frequency, synchronous, step-down switcher with an I2C control interface. The MP8843 can support up to 3A of current from a wide 2.6V-to- 6V input supply range with excellent load and line regulation.

Highly customizable, the MP8843 is capable of supporting a diverse array of low-voltage applications. Users can program it via an MPS I2C GUI; however, changes made in I2C mode will not be retained once the EVB is powered down. Once information is written to the PMIC in OTP mode, it cannot be changed.

The EVKT8843 is a valuable evaluation tool well-suited for all types of experience levels, from beginner to expert, and can help users quickly determine if the MP8843 is right for their target application.
