Features

low-voltage operation. This IC can obtain the step-up voltage with a small number of external components. The minimum operating voltage is as low as 1.8 V so that it can operate with two dry batteries. In addition, since it uses the 16-pin surface mounting type package with 0.65 mm pitch, it is suitable for a miniaturized highly efficient potable power supply. 5.0±0.2 16 9 (1.0) Unit: mm 4.4±0.2 6.4±0.3 0.15 −0.05 +0.10 0° to 10° 0.5±0.2 s Features 0.65 (0.225)
