L4971 is a 1.5A step down switching regulator that delivers 1.5A at a voltage between 3.3V and 50V (selected by a simple external divider). Realized in BCD mixed technology, the device uses an internal power D-MOS transistor (with a typical Rdson of 0.25Ω) to obtain very high efficency and high switching speed.
The L4971 is a monolithic power switching regulator delivering up to 1.5A at an output voltage between 3.3V and 50V. Realized in BCD mixed technology, the device uses an internal power D-MOS transistor to achieve high efficiency and switching speeds up to 300kHz. It features a precise 3.3V internal reference and allows for output voltage adjustment via an external divider.
