LM2596HVS-5.0

UMW · DC-DC Converters · TO-263-5

LM2596HVS-5.0 from UMW, in a TO-263-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input supply voltage. Operating range 4.75V to 60V for the HV version (absolute max 63V). Requires a low-ESR bulk input capacitor (e.g. 680 µF) placed close to the pin.
2 Output power_out Switching output of the internal power transistor. Drives the external catch diode and LC filter (typ. 33 µH inductor plus 220 µF output capacitor) to deliver the regulated 5.0V, 3A output. Saturation voltage ~1.16V at 3A; peak current limit typ. 4.5A.
3 GND power_in Ground return for the device and reference for VIN, Output, Feedback and ON/OFF pins. On TO-263 this pin is also connected to the exposed tab.
4 Feedback input Output voltage feedback sense input. For the fixed 5.0V version this pin is tied directly to the regulated output node; internal divider sets VOUT = 5.0V. Absolute max -0.3V to +25V; feedback bias current 10 nA typ (adjustable version).
5 ON/OFF input Active-low shutdown / enable input. Regulator is ON when the pin is low (<=0.6V) or left floating; regulator is OFF (standby, IQ ~80 µA) when driven high (>=2V). TTL-compatible; absolute max -0.3V to +25V. Input current typ. 5 µA at 2.5V.
