ROHM has developed what it says is a high efficiency power management IC optimised for Freescale Semiconductor's i.MX 6SoloLite applications processor. The processor is offered as an application platform for battery-driven applications where power consumption is crucial such as e-books, wearable tech, tablets, portable terminals for industrial equipment, and other portable devices.

The BD71805MWV uses power supply technology cultivated for mobile applications to optimise circuit configuration for the i.MX 6SoloLite processor. The result is significantly reduced power consumption during both standby and normal operation, prolonging battery life considerably, noted the company.

One of the most important considerations in the design of portable devices is maximising battery life in order to increase operating time. However, reducing the power consumption of individual components to minimise energy expenditure has proven to be particularly challenging. And although Freescale's i.MX 6SoloLite processor has been adopted in a variety of mobile equipment to provide energy-efficient operation, there are increasing demands to decrease power consumption even further.


The BD71805MWV leverages ROHM's analogue technology to achieve an ideal power supply system for driving Freescale's i.MX 6SoloLite processor.

In response, the BD71805MWV leverages ROHM's analogue technology to achieve an ideal power supply system for driving the i.MX 6SoloLite processor. This results in a power conversion efficiency of over 82 per cent (during normal operation) and a reduction in standby current consumption by 45 per cent versus conventional products, both keys to lowering overall power consumption, stated ROHM.

In addition, an real time clock (RTC) function that enables clock and calendar management without driving the main processor is built in, increased operating time, along with a Li-ion battery charger featuring 30V input overvoltage protection that eliminates the need for an external IC, reducing footprint by 20 per cent and contributing to greater miniaturisation.

Sample price of the BD71805MWV is at $5. Samples are available with OEM quantities set for April 2015.
