PRODUCTION DATA
The regulation of the positive charge pump (CPP) can be done either on the input (transistor placed between VDD and the diode) or on the output. For better regulation and fewer interactions between the boost converter and the CPP controller, it is recommended to place the transistor on the output. During startup, the inrush current is limited by the SWP push-pull stage that limits the current to 300 mA typically. For proper operation, it is recommended to have a headroom (2xVDD-2xVDIODE-VGH) of 1 V minimum.
