Description

The RPX-1.0 is a buck converter with an integrated inductor in a compact 3mm x 5mm x 1.6mm thermally-enhanced QFN package. The input range is from 4 to 36VDC, allowing 5V, 12V, or 24V supply voltages to be used. The output voltage can be set with two resistors in the range from 0.8 up to 30VDC. The output current is up to 1A and is fully protected against continuous short-circuits, output overcurrent, or over-temperature faults.

3 The reflow time period during peak temperature of 240°C ±5°C

should not exceed 30 seconds. 4 Reflow time above liquids (217°C) should not exceed 150 seconds.

5 For solder paste use a standard SAC Alloy such as SAC 305, type 3 or

higher. 6 Other soldering methods (e.g. vapor-phase) are not verified and have to validate by the customer on his own risk. PCB LAYOUT SUGGESTION continued on next page Efficient PCB layout, especially of the input capacitor placement, is critical for stable operation. For best results, refer to Figure 6, and follow the guidelines below. 1. Connect a large ground plane to GND pins 14 and 15 directly. If the bottom layer is a ground plane, add vias near GND. 2. Ensure that the high-current paths at GND and VIN have short, direct, and wide traces. 3. Place the ceramic input capacitor close to VIN and GND. 4. Keep the connection of the input capacitor and VIN as short and wide as possible. 5. Place the external feedback resistors next to FB. 6. Feedback and switch node should be placed as far away from one another as possible.
