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 specified, the following conditions apply: VIN = SHDN = 12V PARAMETER TEST CONDITIONS MIN TYP MAX UNIT VIN (Input Power Supply) VIN Operating input voltage 4 60 V ISHDN Shutdown supply current VEN = 0 V 1 3 µA IQ Operating quiescent current (non-switching) no load, VIN = 12 V 28 µA UVLO Undervoltage lockout thresholds Rising threshold 4 V Falling threshold 3 SHDN VSHDN_Thre Rising SHDN Threshold Voltage 1.05 1.25 1.38 V ISHDN Input current SHDN = 2.3 V -4.2 µA SHDN = 0.9 V -1 ISHDN_HYS Hysteresis current -3 µA HIGH-SIDE MOSFET RDS_ON On-resistance VIN = 12 V, CB to SW = 5.8 V 900 m Ω VOLTAGE REFERENCE (FB PIN) VFB Feedback voltage 0.747 0.765 0.782 V CURRENT LIMIT ILIMIT Peak Current limit VIN = 12 V, TJ = 25°C 1200 mA 1700 THERMAL PERFORMANCE TSHDN (1) Thermal shutdown threshold 170 ºC THYS (1) Hysteresis 10 ºC (1) Ensured by design. 7.6 Switching Characteristics over operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT SW (SW PIN) fSW Switching frequency LMR16006X 595 700 805 kHz LMR16006Y 1785 2100 2415 TON_MIN (1) Minimum turn-on time fSW = 2.1 MHz 80 ns DMAX Maximum duty cycle LMR16006X 96% LMR16006Y 97% |
