5 / 20 page Electrical Characteristics Note: 1. Maximum package power dissipation limits must be observed. 2. Adjust V CC above the Start-Up threshold before setting to 15V. 3. Low duty cycle pulse technique are used during test to maintain junction temperature as close to ambient as possible. T low = -20+ ,Thigh = +85+ 4. This parameter is measured at the latch trip point with V FB = 0V. V Output Compensation 5. Comparator gain is defined as : Av = V Current Sense Input CHARACTERISTIC SYMBOL MIN TYP MAX UNIT OUTPUT SECTION Output Voltage Low State (Isink=20mA) VOL -0.1 0.4 (Isink=200mA) - 1.6 2.2 High State (Isource=20mA) VOH 13 13.5 - (Isource=200mA) 12 13.4 - Output Voltage with UVLO Activated VCC=6.0V,Isink=1.0mA Output Voltage Rise Time (CL=1.0nF,TJ=25 +) tr - 50 150 ns Output Voltage Fall Time (CL=1.0nF,TJ=25 +) tf - 50 150 ns UNDERVOLTAGE LOCKOUT SECTION Start-Up Threshold TS3842B 14.5 16 17.5 TS3843B 7.8 8.4 9.0 Minimum Operating Voltage After Turn-On TS3842B 8.5 10 11.5 TS3843B 7.0 7.6 8.2 PWM SECTION Duty Cycle Maximum DCmax 94 96 - Minimum DCmin - - 0 TOTAL DEVICE Power Supply Current Start-Up, VCC= 14V - 0.25 0.5 Operating (Note 2) - 12 17 Power Supply Zener Voltage (ICC=25mA) Vz 30 36 - V V VOL(UVLO) % ICC mA Vth V VCC(min) V -0.1 1.1 V VCC=15V (Note 2), RT=10K, CT=3.3nF, TA=Tlow to Thigh (Note 3), unless otherwise noted. |
