| BD83070GWL, Ultra-low Power Boost/Step-down Power IC
| Equipped with ROHM X Ramp PWM control technology
Mass production to reach 1 million units per month starting in October


A DC/DC converter with a power conversion efficiency of 97% is being released.

Battery-powered electronic devices are being used in various fields. These small devices are strongly required to be miniaturized to secure space for new functions and to have low power consumption to extend battery life.
ROHM BD83070GWL DC/DC Converter

ROHM announced on the 10th that it has developed the 'BD83070GWL', a MOSFET-embedded boost/buck DC/DC converter for mobile, wearable, and IoT applications.

A DC/DC converter is a type of power IC that has the function of converting voltage from direct current (DC) to direct current.
The necessity of step-up/step-down DC/DC converters

Lowering the voltage is called step-down, and raising it is called step-up.

Step-up and step-down voltage converters can switch between step-up and step-down based on the input voltage, but because the circuit becomes complex, issues regarding responsiveness and current consumption must be addressed.

BD83070GWL is an ultra-low power boost/buck power IC for electronic devices powered by small batteries.

The BD83070GWL, which incorporates a low-loss MOSFET using a 0.13µm BiCDMOS power process, is equipped with a low-power circuit and has a power conversion efficiency of 97% when the load current is 200mA.
Comparison of Power Conversion Efficiency According to Load Current

In addition, it is equipped with ROHM’s proprietary control technology, ‘X Ramp PWM control,’ enabling seamless step-up and step-down switching according to the input voltage, and the current consumption is only 2.8µA.

Sample shipments of the new product began in April 2019, and mass production is scheduled to begin in October 2019 with a production capacity of 1 million units per month.
ROHM BD83070GWL-EVK-001 Evaluation Board

The evaluation board 'BD83070GWL-EVK-001'Online sales of o; have already started, and it can be purchased from component distribution sites such as chip 1 stop, Corestaff, and RS Components.

Meanwhile, ROHM has released the boost power IC 'BU33UV7NUX' and the step-down power IC 'BD70522GUL' for mobile devices.
