LD7282 6/16/2006 VFM STEP-UP DC/DC CONVERTER REV: 01a General Description The LD7282 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. With a built-in switching MOSFET, the LD7282 takes only three external components (using a coil, diode & capacitor connected externally) to achieve the low ripple & high efficiency. As well, using chip enable function will make it possible to supply current on standby minimized. This converter also features a very low switch off, bias current of 5.0µA typical. Features • Minimum external component counts • Ultra low input current in switch off (Typ.
