General Description
The LD7280 is a VFM step-up DC/DC converter with ultra low supply current. The CMOS design results in less power consumption and high capability for battery-powered instruments.
The LD7280 is a high efficiency step–up DC/DC converter and takes only three external components to achieve the low ripple.
As well, using chip enable function will make it possible to supply current on standby minimized.
Features
• Minimum external component counts
• Ultra low input current in switch off (TYP 5μA)
• ±2% High accuracy of output voltage
• Low ripple and low noise
• Low start-up voltage, 0.85V at no load.
• 80% efficiency with low cost inductor
