BMR46 series PoL Regulators
EAB/FJB/GM (Ksenia Harrisen)
Input 4.5-14 V, Output up to 50 A / 165 W
Note 1: See section I2C/SMBus Setup and Hold Times – Definitions.
Note 2: Monitorable over PMBus Interface.
Note 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. See Operating Information and AN302 for
other fault response options.
Note 4: T
is the switching period.
sw
Note 5: Within +/-3% of V
O
Note 6: See section Soft-start Power Up.
Note 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.
Note 8: See section Over Temperature Protection (OTP).
Note 9: See section External Capacitors.
Note 10: See section Initialization Procedure.
Note 11: See graph Output Ripple vs External Capacitance and Operating information section Output Ripple and Noise.
Note 12: See graph Load Transient vs. External Capacitance and Operating information section External Capacitors.
Note 13: Time for reaching 100% of nominal Vout.
Note 14: For Vout < 1.0 V accuracy is +/-10 mV. For further deviations see section Output Voltage Adjust using PMBus.
Note 15: Accuracy here means deviation from ideal output voltage level given by configured droop and actual load. Includes line, load and temperature variations.
Note 16: For current sharing the Output Voltage Delay Time must be reconfigured to minimum 15 ms, see AN307 for details.
Note 17: For steady state operation above 1.05 x 3.3 V, please contact your local Flex sales representative.
Note 18: A minimum load current is not required if Low Power mode is used (monitoring disabled).
Note 19: See sections Dynamic Loop Compensation and Power Good.
Note 20: Please check with your local flex Sales representative if you intend to adjust the frequency exceed 320 KHz.
