Description

DCDC Register 2

Fields

LOOPCTRL_DC_FF

Two’s complement feed forward step in duty cycle in the switching DC-DC converter

LOOPCTRL_EN_RCSCALE

Enable RC Scale

LOOPCTRL_RCSCALE_THRSH

Increase the threshold detection for RC scale circuit.

0 (no_increase_thrsh): Do not increase the threshold detection for RC scale circuit.

1 (increase_thrsh): Increase the threshold detection for RC scale circuit.

LOOPCTRL_HYST_SIGN

Invert the sign of the hysteresis in DC-DC analog comparators.

0 (noinvert): Do not invert sign of the hysteresis

1 (invert): Invert sign of the hysteresis

BATTMONITOR_EN_BATADJ

This bit enables the DC-DC to improve efficiency and minimize ripple using the information from the BATT_VAL field

DISABLE_PULSE_SKIP

Disable Pulse Skip

0 (idle): DCDC will be idle to save current dissipation when the duty cycle get to the low limit which is set by NEGLIMIT_IN.

1 (not_idle): DCDC will keep working with the low limited duty cycle NEGLIMIT_IN.

DCM_SET_CTRL

DCM Set Control
