LM2853MH-1.5

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

LM2853MH-1.5 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 Input voltage for the control circuitry; AVIN to GND is specified at 3 V to 5.5 V and PVIN must always be equal to or less than AVIN.
2 EN input Enable input with an internal pullup, so the device is automatically enabled unless an external enable voltage is applied; VIH is 75% of AVIN minimum and VIL is 25% of AVIN maximum.
3 SGND power_in Low-noise ground for the control circuitry, which must be tied together with the other ground connections on a broad ground plane.
4 SS passive Soft-start pin connected to the reference voltage node with 20 pF of internal capacitance; an external soft-start capacitor between 1 nF and 50 nF is recommended.
5 NC unconnected No connect pin that the datasheet states must be tied to ground.
6 PVIN power_in Input voltage for the power circuitry; PVIN to GND is specified at 1.5 V to 5.5 V.
7 PVIN power_in Input voltage for the power circuitry; PVIN to GND is specified at 1.5 V to 5.5 V.
8 SW output Switch node connected to the output inductor; it should be connected with a short, wide trace to limit losses and EMI.
9 SW output Switch node connected to the output inductor; it should be connected with a short, wide trace to limit losses and EMI.
10 PGND power_in Power ground for the output power FETs, which must be tied together with all other ground connections.
11 PGND power_in Power ground for the output power FETs, which must be tied together with all other ground connections.
12 NC unconnected No-connect pin that the datasheet states must be tied to ground.
13 NC unconnected No-connect pin that the datasheet states must be tied to ground.
14 SNS input Output voltage sense pin, which should be connected as close to the load as possible and away from high dV/dt or dI/dt nodes such as the switch node.
15 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
