(2) Current into VIN pin. (3) This is the static current limit. It can be temporarily higher in applications due to internal propagation delay (see Current Limit and Short Circuit Protection). (4) For fixed voltage versions, the (internal) resistive feedback divider is included. (5) The accuracy in Power Save Mode can be improved by increasing the COUT value, reducing the output voltage ripple. (6) Line and load regulation are depending on external component selection and layout (see Figure 14 and Figure 15). 6.5 Electrical Characteristics over junction temperature range (TJ = –40°C to +125°C), typical values at VIN = 12 V and TJ = 25°C (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT SUPPLY VIN Input voltage range(1) 3 17 V IQ Operating quiescent current EN = High, IOUT = 0 mA, Device not switching 17 30 µA ISD Shutdown current(2) EN = Low 1.8 25 µA VUVLO Undervoltage lockout threshold Falling input voltage 2.6 2.7 2.82 V Hysteresis 180 mV TSD Thermal shutdown temperature 160 °C Thermal shutdown hysteresis 20 CONTROL (EN, PG) VEN_H High-level input threshold voltage (EN) 0.9 V VEN_L Low-level input threshold voltage (EN) 0.3 V ILKG_EN Input leakage current (EN) EN = VIN or GND 0.01 1 µA VTH_PG Power Good threshold voltage Rising (%VOUT) 92% 95% 98% Falling (%VOUT) 87% 90% 93% VOL_PG Power Good output low IPG = –2 mA 0.07 0.3 V ILKG_PG Input leakage current (PG) VPG = 1.8 V 1 400 nA POWER SWITCH RDS(ON) High-side MOSFET ON-resistance VIN ≥ 6 V 300 600 mΩ VIN = 3 V 430 Low-side MOSFET ON-resistance VIN ≥ 6 V 120 200 mΩ VIN = 3 V 165 ILIMF High-side MOSFET forward current limit(3) VIN = 12 V, TA = 25°C 0.85 1.05 1.35 A OUTPUT VREF Internal reference voltage 0.8 V ILKG_FB Pin leakage current (FB) TPS62170-Q1, VFB = 1.2 V 5 400 nA VOUT Output voltage range TPS62170-Q1, VIN ≥ VOUT 0.9 6.0 V Feedback voltage accuracy(4) PWM Mode operation, VIN ≥ VOUT + 1 V –3% 3% Power Save Mode operation, COUT = 22 µF (5) –3.5% 4% DC output voltage load regulation(6) VIN = 12 V, VOUT = 3.3 V, PWM Mode operation 0.05 % / A DC output voltage line regulation (6) 3 V ≤ VIN ≤ 17 V, VOUT = 3.3 V, IOUT = 0.5 A, PWM Mode operation 0.02 % / V |
