## 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:

- 1 Pb-Free assembly is recommended according ro JEDEC J-STD020. 2 Ensure that the peak reflow temperature does not exceed 240°C ±5°C as per JEDEC J-STD020 

- 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 

- 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 PGND 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.
