II. Power Good Output Specifications (Section 1 and Section 2 - Different Values)

The Power Good Output section is the most extensive, with different values provided in each document. I'll list them separately. These values define the timing and voltage thresholds for the Power Good signal.

Section 1 (First Document):

️· Upper Threshold (PWRGD High):
- Minimum: 1.876 V
- Typical: 1.975 V
- Maximum: 2.074 V
- Formula: VID - 125 mV + 5%
️· Lower Threshold (PWRGD Low):
- VID – 125mV - 5% or 0.95 x (VID – 125mV)
- VID – 125mV
- VID – 125mV + 5%
- VID means a specific voltage input value
️· Delay (PWRGD low to PWRGD low): 50 μs to 600 μs
️· Output Low Voltage (PWRGD low):
- Maximum: 0.4 V
- Condition: PWRGDS = 1.0 V, IPWRGOOD = 4.0 mA
️· Power Good Output Tables
* The Power Good section includes multiple tables showing threshold values for various VID settings (e.g., VID4, VID3, VID2, VID1, VID0). These tables are complex and provide specific threshold voltages at various combinations of VID values. (See the full document for these details).
️· Switch Leakage Current: ≤ 1.0 μA at VCC = 14 V, PWRGDS = 1.4 V.
️· Hiccup Latch Discharge Current: 2.0 μA to 10 μA
️· Hiccup Charge / Discharge Ratio: 4.5 to 7.5

Section 2 (Second Document):

️· Upper Threshold (PWRGD High):
- Minimum: 1.330 V
- Typical: 1.365 V
- Maximum: 1.400 V
- Formula: VID – 125mV + 5%
️· Lower Threshold (PWRGD Low):
- VID – 125mV - 5% or 0.95 x (VID – 125mV)
- VID – 125mV
- VID – 125mV + 5%
- VID means a specific voltage input value
️· Power Good Output Tables
* The Power Good section includes multiple tables showing threshold values for various VID settings. (See the full document for these details).
️· Switch Leakage Current: ≤ 1.0 μA at VCC = 14 V, PWRGDS = 1.4 V.
️· Hiccup Latch Discharge Current: 2.0 μA to 10 μA
️· Hiccup Charge / Discharge Ratio: 4.5 to 7.5

III. Voltage Feedback Error Amplifier Specifications

️· VFB Bias Current: 9.5 μA to 11.5 μA
️· Comp Source Current: 15 μA to 60 μA at COMP = 0.5 V to 2.0 V, VFB = 1.6 V.
️· Comp Sink Current: 15 μA to 60 μA at COMP = 0.5 V to 2.0 V, VFB = 1.0 V.

️· Open Loop DC Gain: 60 dB to 95 dB (Guaranteed by design, not tested)
️· Unity Gain Bandwidth: – to 50 kHz (Guaranteed by design, not tested)
️· PSRR @ 1.0 kHz: – to 70 dB (Guaranteed by design, not tested)
️· COMP Max Voltage: 2.4 V to 2.7 V at VFB = 0 V
️· COMP Min Voltage: – to 0.2 V at VFB = 1.6 V
️· COMP Discharge Threshold: – to 0.25 V

Important Considerations

️· Discrepancies: Note that there are some differences in values between the two documents, particularly in the Power Good output specifications (upper and lower thresholds). You should investigate the source and revision of each datasheet to determine which values are correct for your application.
️· Guaranteed by Design: Several specifications are noted as "Guaranteed by Design." This means they are verified through simulations and design analysis but are not explicitly tested in production.
️· Full Datasheets: This summary is based on the provided extracts. You should refer to the complete datasheets for all relevant information, including figures, application circuits, and detailed specifications.
