At the negative output current (bus terminator mode) efficiency of the ZY8110 degrades resulting in increased internal power dissipation. Therefore maximum allowable negative current under specific conditions is 20% lower than the current determined from the derating curves shown in paragraph 5.5. 2 ZD-01991 Rev. 1.1, 01-Jul-10 www.power-one.com Page 3 of 28 ZY8110 10A DC-DC Intelligent POL 8V to 14V Input  0.5V to 5.5V Output Data Sheet 4.3 Protection Specifications Parameter Conditions/Description Min Nom Max Units Output Overcurrent Protection Type Threshold Default Programmable Default Programmable in 11 steps 40 Threshold Accuracy Non-Latching, 130ms period Latching/Non-Latching 140 %IOUT 140 %IOUT -25 25 %IOCP.SET Output Overvoltage Protection Default Programmable Default Programmable in 10% steps 1101 Threshold Accuracy Measured at VO.SET=2.5V -2 Delay From instant when threshold is exceeded until the turn-off command is generated Type Threshold Non-Latching, 130ms period Latching/Non-Latching 130 %VO.SET 130 %VO.SET 2 %VOVP.SET 6 μs Output Undervoltage Protection Default Programmable Default Programmable in 5% steps 75 Non-Latching, 130ms period Latching/Non-Latching 75 %VO.SET 90 %VO.SET Threshold Accuracy Measured at VO.SET=2.5V -2 2 Delay From instant when threshold is exceeded until the turn-off command is generated Type Threshold %VUVP.SET 6 μs Overtemperature Protection Type Default Programmable Turn Off Threshold Temperature is increasing 120 C Turn On Threshold Temperature is decreasing after the module was shut down by OTP 110 C Threshold Accuracy Delay Non-Latching, 130ms period Latching/Non-Latching -5 From instant when the controller junction temperature reaches the OTP threshold until the turn-off command is generated 5 2 C ms Tracking Protection (when Enabled) Type Default Programmable Threshold Enabled during output voltage ramping up Threshold Accuracy Delay ZD-01991 Rev. 1.1, 01-Jul-10 Disabled Latching/Non-Latching, 130ms period -50 From instant when threshold is exceeded until the turn-off command is generated www.power-one.com 250 mVDC 50 mVDC 6 μs Page 4 of 28 ZY8110 10A DC-DC Intelligent POL 8V to 14V Input  0.5V to 5.5V Output Data Sheet Overtemperature Warning Threshold Always enabled, reported in Status register Threshold Accuracy -5 Hysteresis Delay C 120 From instant when threshold is exceeded until the warning signal is generated C 5 3 C 6 μs Power Good Signal (PGOOD pin) VOUT is inside the PG window VOUT is outside the PG window Default Programmable in 5% steps Logic Lower Threshold High Low 90 90 Upper Threshold Delay From instant when threshold is exceeded until status of PG signal changes Threshold Accuracy Measured at VO.SET=2.5V N/A %VO.SET %VO.SET 95 110 %VO.SET 6 μs -2 2 %VO.SET ___________________ 1 Minimum OVP threshold is 1.0V 4.4 Feature Specifications Parameter Conditions/Description Interleave (Phase Shift) Default Programmable in 11.25 steps Min Nom Max Units 348.75 Degree degree Interleave 0 0 Sequencing Turn ON Delay Turn OFF Delay Default Programmable in 1ms steps Default Programmable in 1ms steps 0 0 255 0 0 63 ms ms ms ms Tracking Turn ON Slew Rate Turn OFF Slew Rate Default Programmable in 7 steps Default Programmable in 7 steps 0.1 -8.331 V/ms V/ms V/ms V/ms 0 13.2 mV/A mV/A Programmable 0.05 50 kHz Programmable 0.05 50 kHz Programmable 0.05 50 kHz Programmable 1 1000 kHz Programmable 1 1000 kHz 0.1 -0.1 -0.1 8.331 Optimal Voltage Positioning Load Regulation Default Programmable in 7 steps 0 Feedback Loop Compensation Zero1 (Effects phase lead and increases gain in mid-band) Zero 2 (Effects phase lead and increases gain in mid-band) Pole 1 (Integrator Pole, effects loop gain) Pole 2 (Effects phase lag and limits gain in mid-band) Pole 3 (High frequency low- pass filter to limit PWM noise) ZD-01991 Rev. 1.1, 01-Jul-10 www.power-one.com Page 5 of 28 ZY8110 10A DC-DC Intelligent POL 8V to 14V Input  0.5V to 5.5V Output Data Sheet Monitoring Voltage Monitoring Accuracy 1 LSB=22mV -1%VOUT – 1 LSB 1%VOUT + 1 LSB mV Current Monitoring Accuracy 30% IOUT NOM
