The Texas Instruments LM2670SX-ADJ is a monolithic integrated circuit designed as a high-efficiency step-down (buck) switching regulator. It is capable of driving loads up to 3A with excellent line and load regulation.
Key electrical specifications include a wide input voltage range from 8V to 40V and an adjustable output voltage from 1.2V to 37V. The regulator operates at a fixed internal oscillator frequency of 260kHz and features an integrated 150mΩ DMOS output switch. Efficiency can reach up to 94%, with a standby current of only 50µA when switched off.
This device is designed for ease of use, requiring only off-the-shelf external components. It is suitable for applications requiring stable and efficient power conversion. The regulator operates within a junction temperature range of -40°C to 125°C.
The LM2670SX-ADJ is available in a surface-mount DDPAK/TO-263-7 package, facilitating integration into various electronic designs.
