5 / 35 page LMZ12010 www.ti.com SNVS667H – FEBRUARY 2010 – REVISED AUGUST 2015 Electrical Characteristics (continued) Limits are for TJ = 25°C unless otherwise specified. Minimum and Maximum limits are ensured 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 TYP MAX UNIT REGULATION AND OVERVOLTAGE COMPARATOR 0.795 In-regulation feedback VSS >+ 0.8 V VFB V over the junction temperature (TJ) 0.775 0.815 voltage IO = 10 A range of –40°C to +125°C Feedback overvoltage 0.86 VFB-OV V protection threshold Feedback input bias 5 IFB nA current Non-switching quiescent 3 IQ mA current Shutdown quiescent 32 ISD VEN = 0 V μA current Dmax Maximum duty factor 85% THERMAL CHARACTERISTICS TSD Thermal shutdown Rising 165 °C Thermal shutdown 15 TSD-HYST Falling °C hysteresis PERFORMANCE PARAMETERS(1) 24 mVP ΔVO Output voltage ripple BW at 20 MHz P ΔVO/ΔVIN Line regulation VIN = 12 V to 20V, IOUT= 10 A ±0.2% 1 mV/ ΔVO/ΔIOUT Load regulation VIN = 12 V, IOUT= 0.001 A to 10 A 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 = 10 A 87.5% (1) EN 55022:2006, +A1:2007, FCC Part 15 Subpart B, tested on Evaluation Board with EMI configuration.
