1W isolated DC-DC converter Fixed input voltage, unregulated single output

Description

B_XT-1WR2 series are specially designed for applications where an isolated voltage is required in a distributed power supply system.They are suitable for

1. Where the voltage of the input power supply is stable(voltage variation:±10%Vin);

2. Where isolation between input and output is necessary(isolation voltage≤1500VDC);

3. Where the output voltage regulation and the ripple&noise of the output voltage is not strictly required;

4. Typical application:digit circuit condition;normal low-frequency artificial circuit condition;relay drive circuit condition, etc.

FEATURES

  • Continuous short-circuit protection
  • Operating ambient temperature range: -40℃ to +105℃
  • Compact SMD package
  • I/O isolation test voltage 1.5k VDC
  • Internal surface mounted design
  • No extra components required
  • Industry standard pin-out
  • IEC62368, UL60950, EN60950 approved
