ROHM BD83070GWL-EVK-001 Converter Evaluation Board is designed to help evaluate the BD83070GWL synchronous buck-boost DC/DC converter. The converter is a power supply solution designed for battery-powered devices. The converter 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 of supporting up to 1A output on pulse width modulation (PWM) and provides high-efficiency for heavy load. It is possible to disable auto-PFM/PWM mode by via MODE pin. User can select from 2 preset output voltages via VSEL pin and it changes between buck and boost operations depending on the relation between the input voltage and output voltage.
