These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltages are with respect to GND. Currents are positive into, and negative out of the specified terminal. electrical characteristics over recommended operating virtual junction temperature range, VDD = 10 V (See Note 1),1-µF capacitor from VDD to GND, RT = 165 kΩ, RF = 1 kΩ, CF = 220 pF, RSET = 50 kΩ, TA = −40°C to 85°C for UCC2808x, TA = 0°C to 70°C for UCC3808x, TA = TJ (unless otherwise noted) overall PARAMETER TEST CONDITIONS MIN TYP MAX UNITS Start-up current VDD < UVLO start threshold voltage 120 200 µA Supply current CTRL = 0 V, CS = 0 V, See Note 1 1.5 2.5 mA undervoltage lockout PARAMETER TEST CONDITIONS MIN TYP MAX UNITS Start threshold voltage UCC38083/5 See Note 1 11.5 12.5 13.5 Start threshold voltage UCC38084/6 4.1 4.3 4.5 Minimum operating voltage UCC38083/5 7.6 8.3 9.0 V Minimum operating voltage after start UCC38084/6 3.9 4.1 4.3 V Hysteresis voltage UCC38083/5 3.5 4.2 5.1 Hysteresis voltage UCC38084/6 0.1 0.2 0.3 oscillator PARAMETER TEST CONDITIONS MIN TYP MAX UNITS Frequency 2 x f(OUTA) 180 200 220 kHz Voltage amplitude See Note 2 1.4 1.5 1.6 V Oscillator fall time (dead time) 110 220 ns RT pin voltage 1.2 1.5 1.6 V |
