Note6: Tested with RECOM evaluation module: RPX-1.0-EVM-1|||| ## OUTPUT VOLTAGE TRIMMING The external resistor divider sets the output voltage (see _“Typical Application”_ ). The feedback resistor (R4) sets the feedback loop bandwidth with the internal compensation capacitor. R3 should be approximately 75k W when VOUT ≥ 1V. The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary. R4 can then be calculated with below equation: **==> picture [526 x 367] intentionally omitted <==** **----- Start of picture text -----**

## PCB LAYOUT SUGGESTION 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. continued on next page REV.: 1/2022 I-9 **www.recom-power.com** **Series** ## **RPX-1.0** ## **DC/DC Converter Series** ~~FY~~ Specifications PCB LAYOUT SUGGESTION ~~PC~~ **==> picture [295 x 10] intentionally omitted <==** **----- Start of picture text -----**
