Variable Documentation

◆ complementFeedForwardStep

uint32_t _dcdc_loop_control_config::complementFeedForwardStep

Available range is 0~7. Two's complement feed forward step in duty cycle in the switching DC-DC converter. Each time this field makes a transition from 0x0, the loop filter of the DC-DC converter is stepped once by a value proportional to the change. This can be used to force a certain control loop behavior, such as improving response under known heavy load transients.

◆ countChargingTimePeriod

dcdc_count_charging_time_period_t _dcdc_low_power_config::countChargingTimePeriod

The period of counting the charging times in power save mode.

◆ countChargingTimeThreshold

dcdc_count_charging_time_threshold_t _dcdc_low_power_config::countChargingTimeThreshold

the threshold of the counting number of charging times during the period that lp_overload_freq_sel sets in power save mode.

◆ enableAdjustHystereticValue

bool _dcdc_low_power_config::enableAdjustHystereticValue

Adjust hysteretic value in low power from 12.5mV to 25mV.

◆ enableCommonHysteresis

bool _dcdc_loop_control_config::enableCommonHysteresis

Enable hysteresis in switching converter common mode analog comparators. This feature will improve transient supply ripple and efficiency.

◆ enableCommonThresholdDetection

bool _dcdc_loop_control_config::enableCommonThresholdDetection

Increase the threshold detection for common mode analog comparator.

◆ enableInvertHysteresisSign

bool _dcdc_loop_control_config::enableInvertHysteresisSign

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

◆ enableLoadResistor

bool _dcdc_internal_regulator_config::enableLoadResistor

control the load resistor of the internal regulator of DCDC, the load resistor is connected as default "true", and need set to "false" to disconnect the load resistor.

◆ enableOverloadDetection

bool _dcdc_low_power_config::enableOverloadDetection

Enable the overload detection in power save mode, if current is larger than the overloading threshold (typical value is 50 mA), DCDC will switch to the run mode automatically.

◆ enableRCScaleCircuit

uint32_t _dcdc_loop_control_config::enableRCScaleCircuit

Available range is 0~7. Enable analog circuit of DC-DC converter to respond faster under transient load conditions.

◆ enableRCThresholdDetection

bool _dcdc_loop_control_config::enableRCThresholdDetection

Increase the threshold detection for RC scale circuit.

◆ enableUseHalfFreqForContinuous

bool _dcdc_min_power_config::enableUseHalfFreqForContinuous

Set DCDC clock to half frequency for the continuous mode.

◆ enableXtalokDetection

bool _dcdc_detection_config::enableXtalokDetection

Enable xtalok detection circuit.

◆ feedbackPoint

uint32_t _dcdc_internal_regulator_config::feedbackPoint

Available range is 0~3. Select the feedback point of the internal regulator.

◆ OverCurrentThreshold

dcdc_over_current_threshold_t _dcdc_detection_config::OverCurrentThreshold

The threshold of over current detection.

◆ PeakCurrentThreshold

dcdc_peak_current_threshold_t _dcdc_detection_config::PeakCurrentThreshold

The threshold of peak current detection.

◆ powerDownLowVlotageDetection

bool _dcdc_detection_config::powerDownLowVlotageDetection

Power down low-voltage detection comparator.

◆ powerDownOverCurrentDetection

bool _dcdc_detection_config::powerDownOverCurrentDetection

Power down over-current detection.

◆ powerDownOverVoltageDetection

bool _dcdc_detection_config::powerDownOverVoltageDetection

Power down over-voltage detection comparator.

◆ powerDownPeakCurrentDetection

bool _dcdc_detection_config::powerDownPeakCurrentDetection

Power down peak-current detection.

◆ powerDownZeroCrossDetection

bool _dcdc_detection_config::powerDownZeroCrossDetection

Power down the zero cross detection function for discontinuous conductor mode.
