Thermal Design Guide
Locate your operating current, read the junction temp
rise from the graph and add to your maximum ambient.
135°C is the maximum allowable operating junction tem-
perature. Test conditions: Device soldered into 4” x 4”
PCB, 2 sided with power and ground planes for heat con-
duction. Due to the difficulty in predicting the thermal
effects of airflow velocity and direction, and thermal con-
duction through ground planes it is important that the SS26
SuperSIPTM be evaluated thermally in each application.
For high ambient temperature/high current application
please request our Application Note 35-118-01, “Accurate
Measurements of SS26 SuperSIPTM Junction Tempera-
ture”, for further assistance.
Programming
To program the SS26 SuperSIPTM for Vout<3.3, connect
resistor across pins 8 (TRIM) and 6 (Vo). For Vout>3.3,
resistor is connected across pins 8 and 4 (Gnd).
