The input range is from 3.0 to 18VDC, allowing 5V and 12V supply rails to be used. The output voltage can be set with two resistors in the range from 0.8V up to 5.2V. The output current is up to 3A and is fully protected against continuous short-circuits, output overcurrent or over-temperature faults. Its high current and small size make the RPL-3.0 ideal for imaging systems, distributed power architectures, portable equipment in telecom as well as industrial applications. ## **DC/DC Converter** ## **RPL-3.0** ## **3.0 Amp 10 Pad LGA Package** ## Selection Guide |Part|Input|Output|Output|Efficiency(1)| |---|---|---|---|---| |Number|Voltage Range|Voltage|Current max.|typ.| ||[VDC]|[VDC]|[mA]|[%]| |RPL-3.0|3.0-18.0|0.8-5.2|3000|89| ||Notes:|||| Note1: Efficiency tested at VIN= 12VDC, full load and VOUT= 3.3VDC ## Model Numbering **==> picture [83 x 49] intentionally omitted <==** **----- Start of picture text -----**

Note5: A 10µF input capacitor (CIN) is required to absorb the input switching current. A 22µF output capacitor (COUT) is mandatory. To get stable regulation use for R1 and R2 1% or 0.1% resistors, R4 should be 1kOhm. RECOM recommends low ESR X5R or X7R ceramic caps. ## Safe Operating Area **==> picture [259 x 196] intentionally omitted <==** **----- Start of picture text -----**

## PCB LAYOUT SUGGESTION Effcient PCB layout is critical for stable operation. For the best results, see Figure below and follow the guidelines below: 1. Keep the connection of the input ground and -VIN as short and wide as possible. 2. Ensure that all feedback connections are short and direct. 3. Place the feedback resistors as close to the chip as possible. 4. Route sensitive analog areas such as FB away from SW. 5. Place enough vias around the chip to improve thermal performance. **==> picture [283 x 10] intentionally omitted <==** **----- Start of picture text -----**
