Fixed 1.875 V rail — no divider resistors needed
1 MHz switching — inductor size vs ripple trade-off
Switching at 1 MHz lets the designer use a small, low-profile inductor — typically a 2.2 µH to 4.7 µH chip inductor in the 0805 or 1210 footprint — which keeps the total solution height under 1.2 mm. The trade-off is higher switching losses at light loads compared to a 500 kHz part, but the synchronous rectifier helps maintain efficiency above 85% down to about 50 mA load.

It is not qualified for automotive under-hood or extended 105°C environments.
No direct replacement or second-source cross-reference is published by TI; the TPS62200 family shares the same pinout but offers different fixed output voltages, so a BOM change would require a different order code.
