Product details

3.9 mOhm load switch for point-of-load distribution

Its headline spec is a 3.9 mOhm typical on-resistance, which keeps conduction losses under 0.4 W at 10 A continuous output — the thermal budget fits a 10-WSON package with exposed pad if the board copper is adequate.

Power Good and slew rate — sequencing without a supervisor

The integrated Power Good output asserts when the output voltage rises above a threshold, letting downstream loads be enabled in sequence without a separate voltage supervisor. The slew rate is controlled by an external capacitor on the CT pin, which sets the turn-on ramp and limits inrush current into bulk capacitance on the output.

The On/Off interface is non-inverting and does not require a separate Vcc supply.

10-WSON package — footprint and thermal path

The 10-WFDFN with exposed pad (3 mm x 2 mm body) is a low-profile surface-mount package suited for dense boards.

Frequently asked questions

What is the on-resistance (Rds on) of TPS22990NDMLR?

The typical Rds(on) is 3.9 mOhm at the rated load voltage and 25°C junction. This value increases with temperature per the normalised curve in the datasheet — budget for ~5.5 mOhm at 105°C junction if running near the 10 A limit.

Does TPS22990NDMLR have a Power Good output?

Yes, the Power Good feature is integrated. The PG pin asserts a logic-high when the output voltage rises above the PG threshold, enabling downstream sequencing without an external supervisor.
