LM61440AASQRJRRQ1 Allgemeine Beschreibung

The LM61440-Q1 includes auto-mode functionality that facilitates frequency foldback during light loads, reducing unloaded current consumption to a mere 7 µA (typical) and enhancing light load efficiency. This seamless transition between PWM and PFM modes, combined with low MOSFET ON resistances and an external bias input, ensures exceptional efficiency across the entire load spectrum. Whether aiming for improved efficiency at lower frequencies or a compact solution size at higher frequencies, the LM61440-Q1 offers the flexibility to meet diverse operational requirements

Hauptmerkmale

High-performance, low-power comparator
Wide operating temperature range
Low input offset voltage and bias current

The order arrived quickly enough. Arrived in a regular bag with pimples. Everything is safe and sound, the legs are whole and not bent. In work, the goods have not yet been tested, there was not yet an opportunity. Thanks to the seller for the product and the quick shipment.
