Step-down converter with LM2576HV

Product detailed description

Pulse DC/DC converter Buck/Step-down, non-isolated.

Low switching frequency, suitable for car installations.

LM2576HV control circuit in D2PAK-5 housing. The output voltage is continuously adjustable by a multi-turn trimmer.

This module may not function properly in all permissible combinations of input and output voltage and current ranges. Especially if the input and output voltage difference is too large and the input voltage is close to the upper limit of the maximum allowable input voltage. If the power supply will have any failures, first check the suitability of the installed coil for your specific case! In some modes outside the coil set band, the module may be destroyed! For details, refer to datasheet section 8.2.1.3 Application Curves on page 20 and 8.2.2.2.2 Inductor Selection (L1) on page 22. In this module, a 100μH coil is used.
