VFM Step-Up DC/DC Converter
Rev: 00a
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 ponents to achieve the low ripple.
As well, using chip enable function will make it possible to supply current on standby minimized.
Features
- Minimum external ponent 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...
