Data Sheet ADP5073 ABSOLUTE MAXIMUM RATINGS THERMAL RESISTANCE Table 3. Parameter Rating
θJA and ΨJT are based on a 4-layer printed circuit board (PCB) PVIN, AVIN −0.3 V to +18 V (two signals and two power planes) with thermal vias connecting SW PVIN − 40 V to PVIN + 0.3 V the exposed pad to a ground plane as recommended in the GND −0.3 V to +0.3 V Layout Considerations section. θJC is measured at the top of the VREG −0.3 V to lower of AVIN + 0.3 V or +6 V package and is independent of the PCB. The ΨJT value is more EN, FB, SYNC/FREQ, PWRGD −0.3 V to +6 V appropriate for calculating junction to case temperature in the COMP, SLEW, SS, VREF −0.3 V to VREG + 0.3 V application. Operating Junction −40°C to +125°C
