Product details

3A synchronous buck in a 3×3 VSON

Switching at 340 kHz, the part balances inductor size against switching losses. The 10-VSON package with exposed pad (3×3 mm) demands a thermal land on the PCB.

Temperature range and environment

Rated for the industrial temperature span of -40°C to 85°C ambient, this regulator fits factory-floor PLCs, outdoor telecom enclosures, and HVAC controllers. It is not AEC-Q100 qualified, so it is not the pick for under-hood or chassis-mounted automotive designs — for that, the LMR33630APCQRNXRQ1 (AEC-Q100, -40°C to 125°C junction) is a closer fit, though it switches at 2.1 MHz and requires a different inductor selection.

Sourcing posture

The TPS54336ADRCR carries an Active lifecycle status and is ROHS3 compliant. For a BOM freeze, this part is a clean line item — no PCN risk from an impending EOL.

Frequently asked questions

Does TPS54336ADRCR have a synchronous rectifier?

Yes, the TPS54336ADRCR integrates a synchronous rectifier, which improves efficiency and removes the need for an external Schottky diode.

Is TPS54336ADRCR equivalent to LMR33630APCQRNXRQ1?

They are not pin-compatible drop-in replacements. The LMR33630APCQRNXRQ1 is an automotive-grade (AEC-Q100) synchronous buck with a 2.1 MHz switching frequency and a -40°C to 125°C junction temperature range, versus the TPS54336ADRCR's 340 kHz and -40°C to 85°C ambient rating. Both deliver 3A output but target different application tiers and require different inductor and compensation networks.
