LM2696MXAX

Texas Instruments · DC-DC Converters · HTSSOP-16-EP

LM2696MXAX from Texas Instruments, in a HTSSOP-16-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	SW	power_out	Switching node of the internal high-side NMOS switch, which connects to the inductor; CBOOT to SW is rated −0.3 V to +7 V.
2	SW	power_out	Switching node of the internal high-side NMOS switch, which connects to the inductor; CBOOT to SW is rated −0.3 V to +7 V.
3	SW	power_out	Switching node of the internal high-side NMOS switch, which connects to the inductor; CBOOT to SW is rated −0.3 V to +7 V.
4	CBOOT	passive	Bootstrap capacitor input, rated −0.3 V to +33 V to GND.
5	AVIN	power_in	Analog voltage input, specified for 4.5 V to 24 V to GND.
6	EXTVCC	power_out	Output of the internal regulator for decoupling, 3.30 V to 4.00 V (3.65 V typical).
7	FB	input	Feedback signal from the output; the FB pin voltage is 1.225 V to 1.282 V and the pin is rated −0.3 V to +7 V.
8	N/C	unconnected	No connect pin.
9	GND	power_in	Ground pin.
10	SS	passive	Soft-start pin, which sources 0.7 µA to 1.4 µA (1 µA typical) at VSS = 0 V; rated −0.3 V to +7 V.
11	PGOOD	output	Power-good flag, open-drain output; the PGOOD threshold is 91.5% to 95.5% of VFB (rising) and the pin is rated −0.3 V to +7 V.
12	RON	passive	Sets the switch on-time dependent on current; the RON voltage is 0.35 V to 0.95 V.
13	SD	input	Shutdown pin with TTL-compatible shutdown thresholds; rated −0.3 V to +7 V.
14	PVIN	power_in	Power voltage input, specified for 4.5 V to 24 V; PVIN is rated −0.3 V to (AVIN + 0.3 V).
15	PVIN	power_in	Power voltage input, specified for 4.5 V to 24 V; PVIN is rated −0.3 V to (AVIN + 0.3 V).
16	PVIN	power_in	Power voltage input, specified for 4.5 V to 24 V; PVIN is rated −0.3 V to (AVIN + 0.3 V).
17	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
