28 / 47 page  TPS65022 SLVS667B – JULY 2006 – REVISED JANUARY 2016 www.ti.com Bit 1 LDO1 ENABLE LDO1 Enable. This bit is logically AND’ed with the state of the LDO1_EN pin to turn on LDO1. Reset to 1 by a UVLO condition, the bit can be written to 0 or 1 through the serial interface. The bit is reset to 1 when the pin LDO_EN is pulled to GND, allowing LDO1 to turn on when LDO_EN returns high. 7.6.5 CON_CTRL Register Address: 04h (read/write) Default Value: B1h Table 8.

It is also used to control the phase shift between the three converters in order to minimize the input rms current, hence reduce the required input blocking capacitance. The DCDC1 converter is taken as the reference and consequently has a fixed zero phase shift. Table 9.
