RT6-Series 1W, FIXED INPUT, ISOLATED & UNREGULATED DUAL/SINGLE OUTPUT DC-DC CONVERTER UTRALMINIATURE SMD PACKAGE PRODUCT PROGRAM FEATURES Single Voltage Output SMD Package Style Industry Standard Pinout No Heatsink Required 3KVDC Isolation High Power Density Internal SMD construction Temperature Range: -40°C~+85°C No External Component Required RoHS Compliance Input Part Number Voltage (VDC) Nominal RT6-0303S10D3 3.3 Range Output Max Min 3.3 304 30 3.0～3.6 The RT6 Series are specially designed for applications where a group of polar power supplies are isolated from the input power supply in a distributed power supply system on a circuit board. These products apply to: 1) Where the voltage of the input power supply is fixed (voltage variation ≤ ±10%); 2) Where isolation is necessary between input and output (isolation voltage ≤3000VDC); 3) Where the regulation of the output voltage and the output ripple noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits. Efficiency (%, Typ.)

If the actual output power is very small, please connect a resistor with proper resistance at the output end in parallel to increase the load, or use our company’s products with a lower rated output power (E/F_T-W2 Series). Recommended testing circuit If you want to further decrease the input/output ripple, an “LC” filtering network may be connected to the input and output ends of the DC/DC converter, see (Figure 1).

However, the capacitance of the output filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1). 3.3/5 4.7 (VDC) 5 10 12 2.2 9 4.7 - - 12 2.2 - - 15 1 Time ( s ec .)

The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. No parallel connection or plug and play.
