Product Description

K78xx-2000R3 series are high efficiency switching regulators and ideal substitutes for LM78xx series three-terminal linear regulators. The converters feature high efficiency, low loss and there is no need for a heat sink. These products are widely used in applications such as industrial control, instrumentation and electric power.

Note: For input voltage exceeding 30 VDC, an input electrolytic capacitor of 22uF/50V is required to prevent the module from being damaged by voltage spikes.

  • High efficiency up to 96% 
  • No-load input current as low as 0.1mA 
  • Operating ambient temperature range: -40℃ to +85℃
  • Output short-circuit protection 
  • Pin-out compatible with LM78XX linear regulators
  • EN62368 approved
