CUI Inc

│ SERIES: NDM2Z-50 │ DESCRIPTION: AUTO COMPENSATED, DIGITAL DC-DC POL CONVERTER

PRODUCT ELECTRICAL SPECIFICATION, HORIZONTAL (CONTINUED)

Notes:

2: Monitorable over PMBus Interface.

3: Automatic restart ~70 or 240 ms after fault if the fault is no longer present. Continuous restart attempts if the fault reappear after restart.

4: T

5: Within +/-3% of VO

6: See section Soft-start Power Up.

7: Tracking functionality is designed to follow a VTRK signal with slew rate < 2.4 V/ms. For faster VTRK signals accuracy will depend on the regulator bandwidth.

8: See section Over Temperature Protection (OTP).

9: See section External Capacitors.

10: See section Initialization Procedure.

11: See graph Output Ripple vs External Capacitance and Operating information section Output Ripple and Noise.

12: See graph Load Transient vs. External Capacitance and Operating information section External Capacitors.

13: Time for reaching 100% of nominal Vout.

14: For Vout < 1.0 V accuracy is +/-10 mV. For further deviations see section Output Voltage Adjust using PMBus.

15: Accuracy here means deviation from ideal output voltage level given by configured droop and actual load. Includes line, load and temperature variations.

16: For current sharing the Output Voltage Delay Time must be reconfigured to minimum 15 ms.

17: For steady state operation above 1.05 x 3.3 V, please contact your local CUI sales representative.

18: A minimum load current is not required if Low Power mode is used (monitoring disabled).

19: See sections Dynamic Loop Compensation and Power Good.
