| E_KS-1W5 Series 1.5W, FIXED INPUT ISOLATED & UNREGULATED OUTPUT SIP PACKAGE DC-DC CONVERTER multi-country patent protection RoHS FEATURES Small Footprint SIP Package High Power Density 3KVDC Isolation Temperature Range: -40C to +85C No External Component Required Internal SMD construction RoHS Compliance PRODUCT PROGRAM Input Part Number E0305KS-1W5 Voltage (VDC) Nominal 3.3 Range 3.0-3.6 Voltage (VDC) 5 Output Current (mA) Max 150 Min 15 81 Efficiency (%)(Typ.) APPLICATIONS The E_KS-1W 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.

See detailed operation instructions at Testing of Power Converter section, application notes. Note: 1. All specifications measured at TA=25C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 2. See below recommended circuits for more details.

Test Conditions Min Typ Max 95 Units % 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 (Figure1). -40 -55 1.5mm from case for 10 seconds 15 85 125 300 25 1 Free air convection Plastic (UL94-V0) S C L Vin Cin GND L Cout +Vout 0V -Vout DC DC (Figure 1) L Cout 3500 2.1 K hours g It should also be noted that the inductance and the frequency of the "LC" filtering network should be staggered with the DC/DC frequency to avoid mutual interference. 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).

The simplest method is to connect a self-recovery fuse in series at the APPLICATION NOTE Requirement on output load To ensure this module can operate efficiently and reliably, During operation, the minimum output load is not less than 10% of the full load, and that this product should never be operated under no load! 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. input end or add a circuit breaker to the circuit. No parallel connection or plug and play. MORNSUN reserves the copyright Specifications subject to change without notice. E_KS-1W5 A/0-2008 Page 2 of 2 |
