LM2576SX-5.0-JSM

JSMSEMI · DC-DC Converters · TO-263-5

LM2576SX-5.0-JSM from JSMSEMI, 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 to the switching regulator; absolute maximum 45 V, 4 V to 40 V operating input range per the features list.
2 OUTPUT output Switch output of the regulator that drives the external inductor and catch diode; output to common is limited to -1 V steady state.
3 COMMON power_in Common (ground) pin of the regulator; the package tab is also connected to COMMON.
4 FEEDBACK input Feedback sense input to the error amplifier, connected to the output for fixed options or to the R1/R2 divider for the adjustable option (Vo = 1.23 (1 + R1/R2)).
5 ON/OFF input Active-low enable input that shuts the regulator down when high; the pin voltage must stay between -0.3 V and VIN, with VIH min 2.2 V and VIL max 1.0 V.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
