LM2852YMXAX-1.2

Texas Instruments · DC-DC Converters · HTSSOP-14-EP

LM2852YMXAX-1.2 from Texas Instruments, in a HTSSOP-14-EP. 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 AVIN power_in Chip bias input pin that provides power to the logic of the chip; connect to the input voltage or a separate rail.
2 EN input Enable pin internally pulled up; connect to ground to disable or to AVIN or leave floating to enable the chip.
3 SGND power_in Signal ground.
4 SS input Soft-start pin connected to a small capacitor to control startup; soft-start capacitance range restricted to 1 nF to 50 nF.
5 NC unconnected No connect pin; must be tied to ground or left floating in the application.
6 PVIN power_in Input supply pin connected to the input voltage source for the internal power PFET.
7 PVIN power_in Input supply pin connected to the input voltage source for the internal power PFET.
8 SW output Switch pin that connects to the output inductor.
9 SW output Switch pin that connects to the output inductor.
10 PGND power_in Power ground; connect to an internal ground plane or other large ground plane.
11 PGND power_in Power ground; connect to an internal ground plane or other large ground plane.
12 NC unconnected No connect pin; must be tied to ground or left floating in the application.
13 NC unconnected No connect pin; must be tied to ground or left floating in the application.
14 SNS output Output voltage sense pin that must be connected as close to the load as possible to ensure the voltage at the load is the expected regulated value.
15 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
