7 / 33 page LMZ36002 www.ti.com SNVSA92A – SEPTEMBER 2015 – REVISED SEPTEMBER 2015 Electrical Characteristics (continued) Over -40°C to +105°C free-air temperature, PVIN = 24 V, VOUT = 5 V, IOUT = IOUT max, ƒsw = 500 kHz, CIN1 = 1 x 10-µF, 100-V 1210 ceramic, CIN2 = 1 x 100-µF 100-V electrolytic bulk, and COUT = 3 x 47-µF, 16-V 1210 ceramic (unless otherwise noted). PARAMETER TEST CONDITIONS MIN TYP MAX UNIT THERMAL SHUTDOWN Shutdown Temperature 160 °C TSHUTDOWN Thermal shutdown Hysteresis 10 °C INPUT/OUTPUT CAPACITANCE ceramic 10(4) µF CIN External input capacitance non-ceramic 100 µF Ceramic 64(5) Note(6) µF Non-ceramic 100 Note(6) µF COUT External output capacitance ceramic + non-ceramic Note(6) µF Equivalent series resistance (ESR) 20 m Ω (4) The specified minimum ceramic input capacitance represents the standard capacitance value. The actual effective capacitance after considering the effects of DC bias and temperature variation should be ≥ 4.7 µF. (5) The amount of required output capacitance varies depending on the output voltage (see Output Capacitor Selection ). The minimum required output capacitance must be comprised of ceramic capacitance. The amount of required ceramic capacitance represents the standard capacitance value. Locate the capacitance close to the device. Adding additional ceramic or non-ceramic capacitance close to the load improves the response of the regulator to load transients. (6) The maximum allowable output capacitance varies depending on the output voltage (see Output Capacitor Selection ). 6.6 Switching Characteristics over operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT ƒSW Switching frequency RT and RTSEL pins open 410 500 590 kHz ƒCLK Synchronization frequency 200 1000 kHz VCLK-H CLK high level 2 5.5 V CLK Control VCLK-L CLK low level 0.4 V DCLK CLK duty cycle 10% 50% 90% Copyright © 2015, Texas Instruments Incorporated Submit Documentation Feedback 7 Product Folder Links: LMZ36002 |
