K78-1000R3: The new 1A switching regulator 

MORNSUN extends its portfolio of non-isolated switching regulator DC/DC Converter with a new series: K78-1000R3. As K78-500R3(500mA output) has enjoyed great popularity from the market, K78-1000R3(1A output) series is designed to meet wider output power range requirement of customers’ application.

Same as K78-500R3, K78-1000R3 series are in SIP package with high efficiency up to 96%, which do not need heat sink. The product has pin-outs compatible with LM78XX regulator in a much smaller size, which saves your space. And its operating temperature ranges from -40°C to +85°C.

The series operate with a wide input voltage range of 6 to 36V and deliver precise output voltages. With standby input current as low as 0.1mA, low ripple & noise and  short-circuit protection, they are suitable for various applications such as:

  • industrial control
  • power grid
  • instrumentation and mining

In addition to encapsulated package, open-frame version is also an available option to save your design cost with more competitive price.

Specifications:

 

  • High efficiency up to 96%
  • No-load input current as low as 0.1mA
  • Operating temperature: -40°C ~ +85°C
  • Negative output available
  • Short-circuit protection
  • Pin-out compatible with LM78XX regulator
  • Meet UL60950/EN60950 standard
