Start-up Operation

DA9233 buck integrates a start-up circuit to minimize output voltage over-shoot and input voltage

drop during start-up. When writing 1 to BUCK_EN (Bit 7 of Reg0x05), the buck is enabled and starts

switching after a typical delay time of 3 ms. During start-up, the cycle-by-cycle current limit is reduced

to limit inrush current.
