To measure the worst-case error amplifier output current, the LM2588 is tested with the feedback voltage set to its low value (specified
in Note 3 under the All Output Voltage Versions Electrical Characteristics () table) and at its high value (specified in Note 2 under the All
When testing the minimum value, do not sink current from this pin—isolate it with a diode. If current is drawn from this pin, the frequency
adjust circuit will begin operation (see Figure 54 ).
Junction to ambient thermal resistance (no external heat sink) for the 7 lead TO-220 package mounted vertically, with ? inch leads in a
socket, or on a PC board with minimum copper area.
Junction to ambient thermal resistance (no external heat sink) for the 7 lead TO-220 package mounted vertically, with ? inch leads
soldered to a PC board containing approximately 4 square inches of (1 oz.) copper area surrounding the leads.
Junction to ambient thermal resistance for the 7 lead TO-263 mounted horizontally against a PC board area of 0.136 square inches (the
same size as the TO-263 package) of 1 oz. (0.0014 in. thick) copper.
Junction to ambient thermal resistance01242001 for the 7 lead TO-263 mounted horizontally against a PC board area of 0.4896 square
inches (3.6 times the area of the TO-263 package) of 1 oz. (0.0014 in. thick) copper.
(10) Junction to ambient thermal resistance for the 7 lead TO-263 mounted horizontally against a PC board copper area of 1.0064 square
inches (7.4 times the area of the TO-263 package) of 1 oz. (0.0014 in. thick) copper. Additional copper area will reduce thermal
resistance further. See the thermal model in Switchers Made Simple ? software.
