Output voltages are factory-programmed to 1.2 V on channel 1 and 1.9 V / 3.3 V on channel 2 (via the VSEL pin), eliminating the feedback resistor divider and saving two components per rail.
The 10-VFDFN exposed pad (3x3 mm body) is the primary heat path. Without the vias, the 2.25 MHz switching losses push the die above the rated limit in still air.
No. It can be designed into new production without obsolescence risk.
The TPS62401DRCT is a pin-compatible sibling in the same dual-buck family. The primary difference is the output voltage programming — the TPS62401DRCT uses a different fixed-voltage configuration. Both share the same package, switching frequency, and current ratings. For a drop-in alternative, confirm the output voltage table against your rail requirements.
Yes. The 10-VFDFN (VSON) package includes an exposed thermal pad on the underside.
