Descripción
- FCDC 00047, ADP1864 and ADP1611 Reference Power Design. The ADP1611 and ADP1864 boost switching power controllers generate positive and negative voltage rails respectively, which is ideal for powering multiple ADC and Op-Amps, ADP1864 switches at 580kHz with a duty cycle of 58% and 70% when generating -7V and -12V respectively. ADP1611 circuit operates at 58% and 29% when generating +12 and +7 respectively
