The TPS24772RGET comes in a 24-VFQFN Exposed Pad package (24-VQFN 4x4 mm body). Without this connection, the junction-to-board thermal resistance climbs and the controller derates earlier in the temperature band. The single-channel controller has no internal pass FET — the external N-channel MOSFET and sense resistor are selected by the designer for the load current and the inrush profile.
Temperature grade and what it means for the BOM
A base-station power card or an outdoor edge gateway that sees 85°C ambient with self-heating still has margin before the thermal shutdown threshold. The 2.95 mA supply current (typ) is the controller's own draw; the external MOSFET's gate drive comes from the charge pump, not the VCC rail, so the quiescent load on the backplane stays low even during startup. Programmable features include current limit, fault timeout, overvoltage protection (OVP), slew rate, and undervoltage lockout (UVLO). These are set with external resistors and a capacitor on the TIMER pin — no I²C or PMBus interface. The auto-retry feature means the controller re-attempts startup after a fault timeout, which suits redundant power architectures where a momentary overload clears itself.
Active lifecycle and compliance documentation
The device is ROHS3 Compliant. Standard TI compliance documentation (RoHS, REACH, material declaration) is available through the TI website or via the distributor's compliance team at RFQ. The 24-VQFN carrier tape pocket is 7-inch or 13-inch reel depending on the order quantity.
