Synchronous Buck-Boost DC/DC Converter with 2 A Switches (VIN = 2.0 V to 5.5 V, 1ch)
BD83070GWL
Synchronous Buck-Boost DC/DC Converter with 2 A Switches (VIN = 2.0 V to 5.5 V, 1ch)
The BD83070GWL was developed to be the de facto standard for low power eco devices used in compact battery-driven applications. Original control technology (X Ramp PWM Control) enables seamless buck-boost transition while built-in low current circuitry achieves an industry-best power conversion efficiency of 97% during operation (200mA load current) along with class-leading 2.8uA current consumption. This contributes to longer operating time in compact battery-driven devices - by as much as 1.14x over standard products during standby (100uA load current).

- Evaluation Board - BD83070GWL-EVK-001
The BD83070GWL converter is a power supply solution designed for battery powered devices. It can operate at pulse frequency modulation (PFM) to suppress loss and current consumption during light load which has 2.8µA quiescent current at no load. Capable to support up to 1A output on pulse width modulation (PWM) and provides high efficiency for heavy load.
