Frequently Asked Questions
What is the input voltage range of the LM2576HVT-15/NOPB?
The LM2576HVT-15/NOPB accepts an input voltage from 4V minimum to 60V maximum, with a nominal operating voltage of 25V. This wide range makes it suitable for automotive (12V/24V), industrial (24V/48V), and high-voltage DC bus applications.
What output voltage and current does the LM2576HVT-15/NOPB provide?
This device provides a fixed 15V output with a tolerance of ±4% (14.25V to 15.83V) and can supply up to 3A of continuous output current. The switching frequency is 52kHz, enabling the use of compact external inductors and capacitors.
What protection features are built into the LM2576HVT-15/NOPB?
The LM2576HVT-15/NOPB includes internal thermal shutdown protection that disables the device if junction temperature exceeds safe limits, plus cycle-by-cycle current limiting to protect against overload and short-circuit conditions. These features eliminate the need for external protection components in most designs.
What are common alternatives to the LM2576HVT-15/NOPB?
Common alternatives include the LM2596 (3A, higher switching frequency at 150kHz for smaller passives), the LM5576 for higher input voltages, and the TPS54360 for improved efficiency. For pin-compatible options, the LM2576HVT-15 without NOPB suffix is the lead-containing equivalent.
In what package does the LM2576HVT-15/NOPB come, and is it RoHS compliant?
The LM2576HVT-15/NOPB is available in a 5-pin TO-220 (R-PSFM-T5) through-hole package, which provides excellent thermal dissipation. The NOPB suffix indicates it is lead-free (Pb-free) and RoHS compliant, with JESD-609 Code e3 confirming halogen-free construction.
