LP6210
High voltage buck converter with 6V to 40V input range for industrial and automotive applications
Product Overview
Description
The LP6210 is a high voltage buck converter designed for industrial and automotive applications with wide input voltage ranges. It can operate from 6V to 40V input, making it suitable for 12V and 24V systems.
The converter delivers up to 2A output current with adjustable output voltage from 0.8V to 0.9×VIN. The fixed 500kHz switching frequency provides a good balance between efficiency and component size. Peak efficiency reaches 94% at moderate loads.
The LP6210 includes comprehensive protection features including over-current protection, thermal shutdown, and input under-voltage lockout. The enable pin allows external power control. Available in an exposed-pad SOIC-8 package for enhanced thermal performance, it is ideal for industrial control, automotive electronics, and telecom equipment.

FAE Expert Insights
"The LP6210 is my go-to buck converter for industrial applications with 12V or 24V inputs. The 40V maximum input provides good margin for automotive load dump conditions. I've used it in factory automation equipment, vehicle tracking systems, and telecom power supplies. The 2A current capability is sufficient for most industrial subsystems. The 500kHz frequency is a good compromise - lower than 1MHz converters for better efficiency, but still allows reasonably sized inductors. One implementation tip: the exposed pad must be soldered to a large copper area for thermal management. At 24V input and 2A output, the internal MOSFETs dissipate significant power. I've seen designs fail from inadequate heat sinking. The adjustable output is useful - I've generated 5V, 3.3V, and even 1.2V rails from 24V input. Overall, a robust industrial-grade buck converter."
