5 / 35 page LMZ13608 www.ti.com SNVS710I – MARCH 2011 – REVISED DECEMBER 2015 Electrical Characteristics (continued) Limits are for TJ = 25°C unless otherwise specified. 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 = 12 V, VOUT = 3.3 V PARAMETER TEST CONDITIONS MIN(1) TYP(2) MAX(1) UNIT REGULATION AND OVERVOLTAGE COMPARATOR 0.795 In-regulation feedback VSS >+ 0.8 V VFB V over the junction temperature voltage IO = 8 A 0.775 0.815 (TJ) range of –40°C to +125°C Feedback overvoltage VFB-OV 0.86 V protection threshold Feedback input bias IFB 5 nA current Non-switching quiescent IQ 3 mA current Shutdown quiescent VEN = 0 V ISD 32 μA current Dmax Maximum duty factor 85% THERMAL CHARACTERISTICS TSD Thermal shutdown Rising 165 °C Thermal shutdown Falling TSD-HYST 15 °C hysteresis PERFORMANCE PARAMETERS(3) ΔVO Output voltage ripple BW at 20 MHz 24 mVPP ΔVO/ΔVIN Line regulation VIN = 12 V to 20 V, IOUT= 8 A ±0.2% ΔVO/ΔIOUT Load regulation VIN = 12 V, IOUT= 0.001 A to 8 A 1 mV/A η Peak efficiency VIN = 12 V, VOUT = 3.3 V, IOUT = 5 A 89.5% η Full load efficiency VIN = 12 V, VOUT = 3.3 V, IOUT = 8 A 88.5% (3) Refer to BOM in Table 1.
