LM2852XMXA-1.2

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

LM2852XMXA-1.2 from Texas Instruments, in a HTSSOP-14-EP. 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 AVIN power_in Chip bias input that powers the chip logic; connect to the input voltage or a separate rail, with AVIN to GND rated 2.85 V to 5.5 V.
2 EN input Enable pin: connect to ground to disable the chip, or connect to AVIN or leave floating to enable it; it is internally pulled up.
3 SGND power_in Signal ground for the control circuitry.
4 SS input Soft-start pin that sets startup time through a small capacitor, with the soft-start capacitance restricted to 1 nF to 50 nF.
5 NC unconnected No connect; must be tied to ground or left floating in the application.
6 PVIN power_in Input supply pin connected to the input voltage and to the source of the internal power PFET, with PVIN to GND rated 1.5 V to 5.5 V.
7 PVIN power_in Input supply pin connected to the input voltage and to the source of the internal power PFET, with PVIN to GND rated 1.5 V to 5.5 V.
8 SW output Switch pin that connects to the output inductor; keep the switch-node trace short and wide with limited area to balance loss and EMI.
9 SW output Switch pin that connects to the output inductor; keep the switch-node trace short and wide with limited area to balance loss and EMI.
10 PGND power_in Power ground that should connect to an internal ground plane or other large ground plane.
11 PGND power_in Power ground that should connect to an internal ground plane or other large ground plane.
12 NC unconnected No connect; must be tied to ground or left floating in the application.
13 NC unconnected No connect; must be tied to ground or left floating in the application.
14 SNS output Output voltage sense pin that should be connected to the output voltage as close to the load as possible.
15 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
