Frequently Asked Questions
What is the input voltage range of the LM2597HVM-3.3?
The LM2597HVM-3.3 accepts an input voltage from 4.5V to 60V, making it suitable for a wide range of power sources including 12V, 24V, and 48V bus systems commonly found in industrial and automotive applications.
What output voltage and current does the LM2597HVM-3.3 provide?
The LM2597HVM-3.3 provides a fixed 3.3V output with an internal 1A switch. It uses current-mode PWM control at 150kHz to deliver stable regulated output for microcontrollers, FPGAs, and other 3.3V logic circuits.
What package does the LM2597HVM-3.3 come in and is it RoHS compliant?
The LM2597HVM-3.3 is available in an 8-pin SO (R-PDSO-G8) surface-mount package. Note that this specific variant uses JESD-609 code e0, indicating it is not lead-free (Pb-free Code: No), so designers targeting RoHS compliance should verify requirements before selection.
What external components are needed to build a buck converter with the LM2597HVM-3.3?
A typical LM2597HVM-3.3 application requires an external inductor, output capacitor, input capacitor, and a catch diode. Texas Instruments provides reference designs and a design tool (WEBENCH) to help select optimal component values for specific input voltage and load conditions.
