Notes: (1)The DC/DC converter will operate at no load with reduced specifications.  
(2) For optimum voltage accuracy the ‘Remote Sense (+)’ and ‘Remote Sense (–)’ pins must be connected to +Vout and –Vout respectively.  
(3)The Remote On/Off (pin 1) has an internal pull-up, and if it is left open circuit the PT4520 will operastaeppwliehde.nReifnerputto thpeower

(4)External output capacitance is not required for proper operation. Capacitamce may be added to improve threanrsieesnpotsn.sTe hetomaloxaimd umt  
total capacitance (including the load circuit) must not exceed 220µF, and the combined ESR of must not be less than 100mΩ.  
(5)See Safe Operating Area curves or contact the factory for the appropriate derating.  
(6)During solder reflow of SMD package version do not elevate the module case, pins, or internal component tpeemakpeorfa2tu1r5e°sC.aFbovre

further guidance refer to the application note, “Reflow Soldering Requirements for Plug-in Power Surface Mount Products,” (SLTA051).  
(7)The case pins on the through-hole package types (suffixes  
N & A) must be soldered. For more informationacksaegee otuhtelinaepdprliacwabilneg. p
