Product details

Fixed 3.3 V rail, 4 A capable — what that means for the power budget

The ADP2164ACPZ-3.3-R7 is a fixed-output synchronous buck regulator delivering 4 A from a 2.7 V to 6.5 V input rail.

Switching frequency: inductor size vs. efficiency trade

The switching frequency is programmable from 500 kHz to 1.4 MHz.

Temperature grade: -40°C to 125°C junction

Rated for junction temperatures from -40°C to 125°C, this part fits industrial and telecom applications.

Lifecycle and sourcing posture

The ADP2164ACPZ-3.3-R7 carries an Active lifecycle status with ROHS3 compliance.

Frequently asked questions

What is the difference between ADP2164ACPZ-3.3-R7 and ADP2164ACPZ-1.8-R7?

The only parametric difference between these two fixed-output ADP2164 variants is the output voltage: the -3.3-R7 delivers a fixed 3.3 V, while the -1.8-R7 delivers a fixed 1.8 V. Both share the same 4 A output current, 2.7 V to 6.5 V input range, 500 kHz to 1.4 MHz switching frequency, synchronous rectifier, and 16-LFCSP package. They are pin-compatible, so a board designed for one can accept the other by changing only the output capacitor voltage rating.
