    12VDC To 3.3VDC Automotive DC DC Converter Unregulated EN60950 1W

    1W isolated DC-DC with Fixed Input Voltage; unregulated Single Output


    Description


    1. B_S-1WR2&B-D-1WR2 series is designed for use in distributed power supply systems and especially suitable in applications such as pure digital circuits,low frequency analog circuits,relay-driven circuits and data switching circuits,where:

    2. The voltage of the input power supply is relatively stable with avariation of ±10% Vin or less;

    3. An input to output isolation voltage of up to 1500VDC is necessary;

    4. The requirement for a tight output regulation and low ripple&noise is not as strict.


    FEATURES

    • Continuous short-circuit protection
    • High efficiency up to 80%
    • Operating ambient temperature -40℃ to +105℃
    • Compact SIP/DIP package
    • Industry standard pin-out
    • I/O isolation test voltage 1.5k VDC
    • IEC60950, UL60950, EN60950 approval
