LM2576DE-ADJRG

HANSCHIP semiconductor · DC-DC Converters · ESOP-8

LM2576DE-ADJRG from HANSCHIP semiconductor, in a ESOP-8. 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 Unregulated DC input supply. Operating range 7V-40V for LM2576 and up to 55V for LM2576HV. A local input bypass capacitor (typ. 100uF) is required close to this pin.
2 Output output Switching output of the internal 3A power switch. Connects to the external inductor (L1) and freewheeling Schottky diode (e.g. 1N5822) of the buck converter power stage.
3 Feedback input Regulation feedback sense input to the internal error amplifier. For the ADJ variant, tie to the tap of an external R1/R2 divider from Vout to set Vout = 1.23V x (1 + R2/R1); for fixed variants, connect directly to Vout.
4 ~ON/OFF input Active-low TTL-compatible shutdown control. Logic low (or tied to GND) enables the regulator; logic high (up to Vin) puts the part into low-power standby (~50uA typ).
5 Ground power_in Device ground. Tied internally to the other ground pins (5-8) and to the exposed pad on ESOP-8; all should be connected to the PCB ground plane.
6 Ground power_in Device ground. Connect to the PCB ground plane; internally common with pins 5, 7, 8 and the ESOP exposed pad.
7 Ground power_in Device ground. Connect to the PCB ground plane; internally common with pins 5, 6, 8 and the ESOP exposed pad.
8 Ground power_in Device ground. Connect to the PCB ground plane; internally common with pins 5, 6, 7 and the ESOP exposed pad. Multiple ground pins carry the switch return current and aid heat sinking.
