2.5 A Switch Step Down Switching Regulator For Automotive Applications

The A5973D is a step down monolithic power Switching Regulator with a minimum Switch current limit of 2.5 A so it is able to deliver more than 2 A DC current to the load depending on the application conditions. The output voltage CAN be set from 1.235 V to 35 V. The high current level is also achieved thanks to an SO8 package with exposed frame, that allows to reduce the R down to approximately 40 C/W. The th(JA) device uses an internal P-channel D-MOS Transistor (with a typical Rdson of 250 m,) as switching element to minimize the size of the external components. An internal Oscillator fixes the switching frequency at 250 kHz. Having a minimum input voltage of 4 V only, it is particularly suitable for 5 V bus. Pulse by pulse current limit with the internal frequency modulation offers an effective constant current short Circuit Protection Pulse by pulse current limit with the internal frequency modulation offers an effective constant current short Circuit Protection By STMicroelectronics
