5 / 30 page LMZ13608 www.ti.com SNVS710D – MARCH 2011 – REVISED SEPTEMBER 2011 ELECTRICAL CHARACTERISTICS (continued) Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the junction temperature (TJ) range of -40°C to +125°C. Minimum and Maximum limits are specified through test, design or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise stated the following conditions apply: VIN = 12V, VOUT = 3.3V Min Typ Max Symbol Parameter Conditions Units (1) (2) (1) Regulation and Over-Voltage Comparator VFB In-regulation feedback voltage VSS >+ 0.8V 0.775 0.795 0.815 V IO = 8A VFB-OV Feedback over-voltage protection 0.86 V threshold IFB Feedback input bias current 5 nA IQ Non Switching Quiescent Current 3 mA ISD Shut Down Quiescent Current VEN = 0V 32 μA Dmax Maximum Duty Factor 85 % Thermal Characteristics TSD Thermal Shutdown Rising 165 °C TSD-HYST Thermal shutdown hysteresis Falling 15 °C θJA Junction to Ambient (3) Natural Convection 9.9 °C/W 225 LFPM 6.8 500 LFPM 5.2 θJC Junction to Case 1.0 °C/W PERFORMANCE PARAMETERS(4) ΔVO Output voltage ripple BW@ 20 MHz 24 mV PP ΔVO/ΔVIN Line regulation VIN = 12V to 20V, IOUT= 8A ±0.2 % ΔVO/ΔIOUT Load regulation VIN = 12V, IOUT= 0.001A to 8A 1 mV/A η Peak efficiency VIN = 12V VOUT = 3.3V IOUT = 5A 89.5 % η Full load efficiency VIN = 12V VOUT = 3.3V IOUT = 8A 88.5 % (3) Theta JA measured on a 3.0” x 3.5” four layer board, with two ounce copper on outer layers and one ounce copper on inner layers, two hundred and ten 12 mil thermal vias, and 2W power dissipation.
