LM46001AQPWPTQ1

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

LM46001AQPWPTQ1 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 output of the regulator, internally connected to both power MOSFETs; connect to the power inductor.
2 SW power_out Switching output of the regulator, internally connected to both power MOSFETs; connect to the power inductor.
3 CBOOT power_out Bootstrap capacitor connection for the high-side driver; connect a high-quality 470-nF capacitor from CBOOT to SW.
4 VCC power_out Internal bias supply output for bypassing to AGND; do not connect an external load to this pin and never short it to ground during operation.
5 BIAS power_in Optional internal LDO supply input; tie to VOUT for 3.3 V ≤ VOUT ≤ 28 V or to an external 3.3 V or 5 V rail, and tie to ground if not used (VOUT < 3.3 V) without floating it.
6 SYNC input Clock input to synchronize switching to an external clock; use proper high-speed termination and connect to ground if not used, never leave floating.
7 RT passive Connect a resistor from this pin to AGND to program the switching frequency; leave floating for the 500 kHz default.
8 PGOOD output Open-drain power-good flag output; use a 10-kΩ to 100-kΩ pullup to a logic or DC rail no higher than 12 V.
9 FB input Feedback sense input connected to the midpoint of the feedback divider to set VOUT; do not short this pin to ground during operation.
10 AGND power_in Analog ground pin serving as the ground reference for internal references and logic; connect to system ground.
11 SS/TRK passive Soft-start control pin: leave floating for internal soft-start, connect a capacitor to extend soft-start time, or connect an external voltage ramp for tracking.
12 EN input Enable input: high = ON and low = OFF; connect to VIN, through a resistor divider, or to an external voltage or logic source, and do not float.
13 VIN power_in Supply input to the internal LDO and high-side power FET; connect to the power supply and CIN, keeping the path from VIN to CIN and PGND as short as possible.
14 VIN power_in Supply input to the internal LDO and high-side power FET; connect to the power supply and CIN, keeping the path from VIN to CIN and PGND as short as possible.
15 PGND power_in Power ground connected internally to the low-side power FET; connect to system ground, PAD, AGND, and the ground pins of CIN and COUT, with a short path to CIN.
16 PGND power_in Power ground connected internally to the low-side power FET; connect to system ground, PAD, AGND, and the ground pins of CIN and COUT, with a short path to CIN.
17 PAD passive Exposed pad (from the footprint; not named in the datasheet pin table).
