BD83070GWL-EVK-001

Synchronous buck-boost DC/DC converter BD83070GWL evaluation board. 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. It is possible to disable auto-PFM/PWM mode by via MODE pin. User can select from 2 preset output voltage via VSEL pin and it changes between buck and boost operations depending on the relation between input voltage and output voltage.

• Automation PFM/PWM mode and fixed PWM mode
• Output current up to 1A (VIN <gt/> 2.7V, VOUT = 3.3V)
• Input voltage range from 2V to 5.5V
• Selectable output voltage of 2.5V or 3.3V
• Efficiency up to 95%, UVLO detection: 1.61V(max)
• Switching frequency of 1.5MHz (typ)
