Мікросхема L5973D

L5973D

The L5973D is a step down monolithic switching power regulator with a minimum switch current limit of 2.5 A so it is able to deliver more than 2A DC current to the load depending on the application conditions. The output voltage can be set from 1.235 V to 35V. The high current level is also achieved thanks to an SO8 package with exposed frame, that allows to reduce the Rth(j-amb) down to approximately 40°C/W. The device uses an internal P-channel D-MOS transistor (with a typical Rdson of 250 mR) as switching element to minimise the size of the external components. An internal oscillator fixes the frequency switching at 250kHz.
