By Rob GrayMay 22, 2016

Monolithic Power Systems (MPS) recently announced the release of MP 8843 with format part number MP8843GG. Developed for digital power system management, the device with synchronous step-down DC/DC controller, is based on an I2C PMBus interface.

A best-in-class step-down switcher, the MP 8843, with an outstanding load and line regulation, can support up to 3A of current, from a wide range of input supply varying from 2.6V-to-6V. Designed with a unique Constant-on-time (COT) control, the highly integrated, high-frequency device, also provides an excellent high light-load efficiency, with fast transient response.

Communication Interface Speed and Voltage Specification of the MP 8843

Integrated with a power-save selection mode, MP 8843, controls an output voltage of 0.6V to 1.1V on the fly with 3.9mV voltage steps. Suitable to meet a varied range of application requirements, the I2C interface power device, delivers an incredible communication speed up to 3.4Mbps.

MP 8843GG is Packed with a Comprehensive Range of Excellent Features

The MP8843GG device is loaded with unique protection features, such as internal soft start (SS), over-current protection (OCP), and over-temperature protection (OTP). Other distinct features include -

  • Wide Input Range from 2.6V to 6V
  • Up to 3A of Continuous Current
  • 55mΩ and 35mΩ Internal Power MOSFET
