... Dual Output Step-Up/Inverting DC/DC Converter ■GENERAL DESCRIPTION The XC9519 series channel (step-up and inverting) DC/DC converter IC. One DC/DC converter is a step-up DC/DC and the other is an inverting DC/DC converter. The step-up converter compares a built-in reference voltage 1.0V to the FBP voltage (accuracy ±1.5%) and a positive output voltage can be set freely with the external components up to 18V. The inverting DC/DC converter compares a difference between a reference voltage and the FBN voltage (accuracy ± ...
