To disperse the heat, the bottom heatspreader must be soldered to the PCB. Heat flows through the heatspreader to the circuit board copper then spreads and converts to air. Thus the PCB copper plane becomes the heatsink. This has proven to be a very effective technique. A separate application note details the 28 Ld QFN. PCB design considerations are available. θ JA Tj Ta – () PD ----------------------- = 50.4CW = (EQ. 3) ISL59910, ISL59913 |
