The device supports up to 75-mA output current and allows the use of tiny external inductors and capacitors. The wide operating input voltage range of 2 V to 15 V supports energy harvesting, battery powered and as well 9-V or 12-V line powered applications. With its advanced hysteretic control scheme, the converter provides power save mode operation. At light loads the converter operates in pulse frequency modulation (PFM) mode and transitions automa...
