What are the key features of LM2575HVT-ADJEP?
- Wide 8 V to 60 V input range accommodating high-voltage industrial and automotive supply rails
- Adjustable output voltage mode allowing custom regulation from 1.23 V to 57 V with two external resistors
- Integrated PWM voltage-mode controller delivering up to 3.2 A peak current with minimal external components
What is LM2575HVT-ADJEP used for?
The LM2575HVT-ADJEP is well-suited for industrial power supplies, 48 V telecom bus step-down converters, and automotive accessory regulators where a wide input voltage range up to 60 V is required. Its TO-220-5 package with straight leads simplifies heatsinking and point-of-load mounting on through-hole or mixed-technology boards. Designers use it in PLC I/O modules, battery charger auxiliary rails, and high-voltage bench instrument power stages.

Frequently Asked Questions
What is the maximum input voltage the LM2575HVT-ADJEP can handle and why is this relevant for 48 V telecom designs?
The LM2575HVT-ADJEP accepts input voltages from 8 V up to 60 V, comfortably covering the 36 V to 57 V input range of standard 48 V telecom bus systems, plus sufficient margin for load-dump transients, making it a direct drop-in for telecom shelf power supplies without an external input clamp.
How is the output voltage of the LM2575HVT-ADJEP set and what component tolerance affects regulation accuracy?
Output voltage is programmed by a resistor divider from the output to the 1.23 V reference feedback pin, using two external resistors typically in the 1 kΩ to 100 kΩ range. Using 1% tolerance resistors limits output voltage error to within ±2% across the full 8 V to 60 V input range.
When would an engineer choose the LM2575HVT-ADJEP over a fixed-voltage LM2575 variant?
The adjustable EP variant is preferable when the target output voltage is non-standard (for example 3.3 V, 7.5 V, or 15 V), when a single BOM line must serve multiple output rails across product variants, or when fine voltage trimming of ±5% is needed for load-regulation compensation in a 12 V or 24 V output design.
What switching frequency does the LM2575HVT-ADJEP operate at and how does that influence the inductor and capacitor selection?
The LM2575HVT-ADJEP operates at a fixed 52 kHz switching frequency, which calls for an external inductor in the 68 µH to 220 µH range and an output capacitor of at least 100 µF to maintain output ripple below 50 mV at 1 A load, as specified in the typical application circuit.
