Selection Guide

Choose the TPS22997RYZR when you need a high-current load switch (up to 10A) with adjustable slew rate and quick output discharge for applications like SSDs, smartphones, and portable electronics. If you require a lower current (1A) and do not need adjustable slew rate, the TPS22960 is a cost-effective alternative. For applications needing a fixed slew rate and lower current (2A), the TPS22950 may suffice. The TPS22997RYYR is a drop-in alternative with the same specifications but different package suffix. For cross-brand options, the onsemi FPF2895C may be considered, but verify pin compatibility and electrical specifications before use.

Key Differentiators

  • Adjustable slew rate control (vs TPS22950)
  • Low on-resistance of 4mΞ© (vs FPF2895C)

Design Notes

For optimal thermal performance, ensure adequate copper area on the PCB connected to the VIN and VOUT pins. The 10-WQFN-HR package has an exposed pad that should be soldered to a thermal via array to dissipate heat. Place decoupling capacitors (0.1uF and 10uF) close to the VIN and VBIAS pins to filter noise and stabilize the supply.

Do not exceed the maximum input voltage of 5.5V on the VIN pin. The bias voltage (VBIAS) must be within 1.5V to 5.5V for proper operation. When adjusting the slew rate, select the external capacitor (CT) value according to the datasheet formula to achieve the desired rise time. Incorrect CT values can cause excessive inrush current or slow turn-on.

At 10A continuous current, the power dissipation is I^2 * RON = 10^2 * 0.004 = 0.4W. This is manageable, but ensure the PCB layout provides adequate heat sinking. The thermal resistance of the package is not specified in the provided data, so use conservative design margins. For high ambient temperatures, consider derating the current.
