Note
1. To minimize the thermal resistance from mounting base to heatsink [Rth(mb-h)] (DBS version) follow the
recommended mounting instruction: screw mounting preferred; torque = 40 Ncm; use heatsink compound.
CHARACTERISTICS
VP = 15 V; Tamb = 25 °C; VFB = 40 V; voltages referenced to pin 5 (GND); parameters are measured in test circuit
(see Fig.6); unless otherwise specified.
