Product details

6 MHz switching — small passives, tight layout

The TPS62650YFFT is a synchronous buck regulator from Texas Instruments that switches at 6 MHz, which is the key enabler for using a tiny inductor and small ceramic capacitors — the sort of passive set that fits the 9-DSBGA footprint. Output current is rated at 800 mA continuous from a 2.3 V to 5.5 V input range. The synchronous rectifier means you skip the external Schottky diode; the internal FET handles the low-side, which keeps the BOM count down and efficiency up, especially at light loads.

Output voltage options and temperature range

The output is adjustable or programmable, with a minimum fixed voltage of 0.75 V and preset options of 1.05 V and 1.2 V. The maximum output voltage is 1.44 V.

The base product number is TPS62650.

9-DSBGA footprint — layout consideration

The 9-pin DSBGA package is a wafer-level chip-scale package.

Frequently asked questions

Can the TPS62650YFFT output 1.8 V?

No. The maximum output voltage is 1.44 V. The part is designed for sub-1.5 V rails; for a 1.8 V output you would need a different regulator.

Does the TPS62650YFFT have a direct replacement or equivalent?

No direct drop-in replacement is listed. The LMR33630APCQRNXRQ1 is a higher-current (3 A) buck with a lower switching frequency (2.1 MHz) and a different package (wettable flank QFN). It is not pin-compatible but serves a similar function for higher load currents.

What is the switching frequency of the TPS62650YFFT?

The switching frequency is 6 MHz. This high frequency allows the use of small inductors (typically 1 µH or less) and small output capacitors, which is the main reason the part fits in the tiny 9-DSBGA package.
