(2) See Safe Operating Area curves or contact the factory for the appropriate derating. (3) The STBY* control (pin 3) has an internal pull-up and if it is left open circuit the module will operate when input power is applied. The open-circuit voltage is typcially 1.5 V. Consult the related application note for other interface considerations. (4) The module requires a 560µF electrolytic capacitor at the input and 330µF at the output for proper operation in all applications. In addition, the input capacitance, Cin, must be rated for a minimum of 1.2 Arms of ripple current. For transient or dynamic load applications additional capacitance may be necessary. For more information consult the related application note on capacitor recommendations. (5) During solder reflow of SMD package version do not elevate the module case, pins, or internal component temperatures above a peak of 215°C. For further guidance refer to the application note, “Reflow Soldering Requirements for Plug-in Power Surface Mount Products,” (SLTA051). |
