STMICROELECTRONICS L5973D
DC-DC Switching Buck (Step Down) Regulator, Adjustable, 4V-36Vin, 1.235V-35Vout, 2.5Aout, HSOP-8
產品總覽
The L5973D is a step down monolithic power switching regulator with a minimum switch current limit of 2.5A 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 1.235V 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 switching frequency at 250kHz.
