7 / 39 page  LM3263 www.ti.com SNVS837 – JUNE 2013 SYSTEM CHARACTERISTICS (continued) The following spec table entries are specified by design and verifications providing the component values in the Typical Application Circuit are used (L = 1.5 µH, DCR = 120 m Ω, TOKO DFE201610MT-1R5N, CIN = 10 µF, 6.3V, 0402, Samsung CL05A106MP5NUN, COUT = 10 µF + 4.7 µF + 3 x 1.0 µF; 10V, 0402, Samsung CL05A106MP5NUN, CL05A475MPNRN; 6.3V, 0201, TDK, C0603X5R0J105M). These parameters are not verified by production testing. Min and Max values are specified over the ambient temperature range TA = -30°C to 90°C. Typical values are specified at VBATT = 3.8V (= PVIN = SVDD = PACB), VIO = 1.8V, SMPS_CFG = 20h, and TA =25°C unless otherwise stated.
