General Description 
The RS2596 is Monolithic IC that design for a step‐down DC/DC Converter, and own the ability of driving a 3A load without 
additional transistor component. 
 
The  output  version  included  3.3V,  5V,  12V  and  an  adjustable  type.  It  operates  at  a  switching  frequency  of  150KHz  thus 
allowing  smaller  sized  filter  components  than  what  would  be  needed  with  lower  frequency  switching  regulators.  Other 
features include a guaranteed ±4% tolerance on output voltage under specified input voltage and output load conditions, 
and  ±15%  on  the  oscillator  frequency.  Regarding  protected  function,  thermal  shutdown  is  to  prevent  over  temperature 
operating from damage, and current limit is against over current operating of the output switch. 
Features 
● 3.3V, 5V, 12V and adjustable 
● Adjustable version output voltage range: 1.23‐37V 
● ±4% max over line and load conditions 
● 150KHz ±15% fixed switching frequency 
● TTL shutdown capability 
● Operating voltage can be up to 40V 
● Output load current: 3A 
● TO220‐5 and TO263‐5 packages 
● Low power standby mode 
● Thermal‐shunt down and current‐limit protection

This  integrated  circuit  can  be  damaged  by  ESD.  Orister  Corporation  recommends  that  all  integrated  circuits  be  handled  with 
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. 
 
ESD  damage  can  range  from  subtle  performance  degradation  to  complete  device  failure.  Precision  integrated  circuits  may  be  more 
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
