LM2575S-ADJ

Slkor SLKORMICRO Elec · DC-DC Converters · TO-263-5

LM2575S-ADJ from Slkor SLKORMICRO Elec, in a TO-263-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Unregulated input supply pin; the datasheet rates VIN at 45 V absolute maximum, with a 4V to 40V operating input range.
2 OUTPUT power_out Switching output of the internal power transistor that drives the external inductor and catch diode; the steady-state output voltage to common must not go below -1 V.
3 COMMON power_in Ground (common) pin; the package tab is also connected to COMMON.
4 FEEDBACK input Feedback sense input to the error amplifier; the ADJ version regulates this pin to 1.23 V typical (VFB 1.217 to 1.243 V) through an external R1/R2 divider.
5 ON/OFF input Active-low enable input that shuts the regulator down when high; the datasheet gives -0.3 V to VIN as the pin voltage range, with logic low max 1.0 V and logic high min 2.2 V.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
