Selection Guide

Choose the TPS61086DRCR when you need a high-voltage boost converter with a 2-A switch current limit and a small VSON package. It is ideal for applications requiring output voltages up to 18.5 V, such as OLED displays, white LED drivers, and battery-powered devices. If you need a lower switch current (1.5 A) and can accommodate a larger package, the TPS61085PWR or TPS61085DGKR are cost-effective alternatives. For applications with lower output voltage requirements (up to 5.5 V) and similar package, the TPS61200DRCR is a drop-in alternative with lower current capability. The TPS61086DRCT is the same device with a different tape-and-reel suffix, suitable for automated assembly. Always verify pin compatibility and electrical specifications for your specific application.

Same package and pinout as TPS61200DRCR but higher output voltage (vs TPS61200DRCR)

Design Notes

For optimal performance, place the input capacitor (10 µF) and output capacitor (22 µF) as close as possible to the VIN and VOUT pins. The switch node (SW) should have a short, wide trace to minimize parasitic inductance. Use a solid ground plane under the device and connect the exposed pad to the ground plane with multiple vias for thermal and electrical performance.

The TPS61086DRCR can dissipate significant power at high output currents. The exposed pad must be soldered to a large copper area on the PCB to keep the junction temperature within limits. For example, at 2 A switch current and 5 V output from 3.3 V input, power dissipation is approximately 0.5 W, requiring a copper area of at least 1 cm². Ensure adequate thermal vias are used.

Do not exceed the absolute maximum ratings for input voltage (6.0 V) or switch current (2.0 A). The inductor must have a saturation current rating higher than the peak switch current to avoid saturation and efficiency loss. Also, ensure the feedback resistor divider uses 1% tolerance resistors to maintain output voltage accuracy. The soft-start capacitor should be selected to limit inrush current to acceptable levels.
