L4971D013TR

Импульсный понижающий DC-DC стабилизатор, регулируемый, 8В-55В (Vin), 3.3В-50В, 1.5А, SOIC-16.

The L4971D013TR is a step-down monolithic power Switching Regulator delivering 1.5A at a voltage between 3.3 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 0.25R) to obtain very high efficiency and high switching speed. A switching frequency up to 300kHz is achievable. A wide input voltage range between 8 to 55V and output voltages regulated from 3.3 to 50V cover the majority of today's applications. Features of this new generation of DC-to-DC converter include pulse-by-pulse current limit, hiccup mode for short-circuit protection, voltage feed-forward regulation, soft-start, protection against feedback loop disconnection, inhibit for zero current consumption and thermal shutdown.
