The Texas Instruments LM22670 is an efficient step-down (buck) voltage regulator designed for ease of use with minimal external components. It incorporates a 42-V N-channel MOSFET switch capable of delivering up to 3 A of load current.
Key electrical specifications include a wide input voltage range from 4.5 V to 42 V and an adjustable output voltage as low as 1.285 V. The device offers a default switching frequency of 500 kHz, which can be adjusted from 200 kHz to 1 MHz. It features ±1.5% feedback reference accuracy and a typical quiescent current of 25 µA in shutdown mode.
Designed for various applications including industrial control, telecom, and datacom systems, the LM22670 provides excellent line and load regulation. It operates within a junction temperature range of -40°C to 125°C. The regulator includes integrated features such as soft-start and a precision enable pin for simplified control and power sequencing.
The LM22670 is available in surface-mount packages like HSOP and SO PowerPAD-8, facilitating integration into compact designs.
