Electronic devices powered by small batteries, such as mobile and wearable devices, require parts with low power consumption in order to improve their battery life.
ROHM has developed the BD83070GWL buck-boost DC/DC converter IC for lower power consumption.
Advantages of Buck-Boost DC/DC Converters
Buck-boost operations achieve a stable output even as the voltage of the battery decreases.
Features of the BD83070GWL Buck-Boost DC/DC
(Feature 1: Ultra-low power consumption)
With its analog element layout, 0.13 µm power process BiCDMOS, etc., optimized for analog circuitry and power management ICs, the buck-boost power management IC achieves a top-class power consumption of 2.8 µA by utilizing ROHM's analog technology for low power consumption currents.
(Feature 2: High efficiency)
Equipped with our proprietary X Ramp PWM control, which enables seamless buck-boost conversion, this product has a 97% power conversion rate at the load current of a smartphone or tablet PC (200 mA). Even with other loads (between 100 μA and 1 A) it achieves ultra-efficient power conversion of 90% or more.
