Product details

Fixed 5 V boost in a 1.5 mm² footprint

It integrates a 500 mA switch and operates at a 3.5 MHz switching frequency, which keeps the inductor and capacitors small enough to fit alongside the 6-pin DSBGA package on a tight PCB.

500 mA switch current — sizing the load

The 500 mA switch current limit defines the peak inductor current the part can handle. For a 5 V output from a 3.6 V Li-ion cell, expect around 300 mA to 350 mA of continuous output current before the switch hits its limit — enough to power a small sensor module, a Bluetooth LE radio, or a single USB peripheral.

3.5 MHz switching — small passives, clean rail

The 3.5 MHz switching frequency pushes the ripple into the low-MHz band, so a 1 µH inductor and 4.7 µF output capacitor are typically enough to hold the output ripple under 20 mV. That small LC pair fits in a 2×2 mm footprint, matching the DSBGA's own scale.

Frequently asked questions

Is TPS61240YFFR compatible with the base number TPS61240?

Yes — TPS61240YFFR is a specific ordering code within the TPS61240 family. The YFF suffix denotes the 6-pin DSBGA package and the R suffix indicates Tape & Reel packaging. Functionally it is the same boost regulator as other TPS61240 variants, but the package is the smallest option in the family.
