The LT1940NFS is a DC DC switching regulator designed for various power supply applications. It supports step-up, step-down, and step-up/step-down functions, providing flexibility in power conversion.
Key electrical specifications include an adjustable output voltage starting from 0.628V up to 25V (40V switch), an input voltage range of 3.5V to 25V, and a high switching frequency of 1.1MHz. It features 3 outputs and can handle output currents of 1.5A, 2A, or 3A depending on the configuration.
This component is housed in a 28-TSSOP-EP package with an exposed pad, designed for surface mounting. The operating temperature range is from 0°C to 70°C (TA). Its topology includes Buck, Boost, and SEPIC configurations, making it suitable for a wide array of design requirements.
The LT1940NFS is RoHS3 Compliant, though this compliance status is unverified. It is also rated for Moisture Sensitivity Level 1 (Unlimited) and is REACH Unaffected, with these statuses also carrying low confidence.
The input voltage range is 3.5V to 25V.
