E_KS-1W5 Series 1.5W, FIXED INPUT ISOLATED & UNREGULATED OUTPUT SIP PACKAGE DC-DC CONVERTER multi-country patent protection RoHS FEATURES PRODUCT PROGRAM Small Footprint SIP Package High Power Density 3KVDC Isolation Temperature Range: -40°C to +85°C No External Component Required Internal SMD construction RoHS Compliance Input Part Number Output Voltage (VDC) Nominal Range Voltage (VDC) 3.3 3.0-3.6 ±5 E0305KS-1W5 Efficiency (%)(Typ.) Current (mA) Max Min ±150 ±15 81 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. ISOLATION SPECIFICATIONS Such as: purely digital circuits, ordinary low Item Test Conditions frequency analog circuits, and IGBT power Isolation voltage Tested for 1 minute and 1mA max 3000 VDC Isolation resistance Test at 500VDC 1000 MΩ device driving circuits.

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 TYPICAL CHARACTERISTICS 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 input end or add a circuit breaker to the circuit. APPLICATION NOTE Requirement on output load No parallel connection or plug and play. 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.
