LT6658AIDE-1.2#PBF from Analog Devices, in a DFN-16-EP(3x4). 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 GND power_in Main ground connection that should be connected into a star ground or ground plane.
2 GND power_in Main ground connection that should be connected into a star ground or ground plane.
3 BYPASS passive Bypass pin that requires a 1µF capacitor for bandgap stability.
4 DNC unconnected Do not connect; connected internally, so keep leakage current from this pin to a minimum and do not connect external circuitry to it.
5 NR passive Noise reduction pin; a capacitor connected between this pin and ground band-limits the reference noise.
6 GND power_in Main ground connection that should be connected into a star ground or ground plane.
7 VOUT2_S input VOUT2 Kelvin sense pin that should be connected directly to the load.
8 VOUT2_F power_out VOUT2 output that requires a 1µF to 50µF output capacitor for stable operation and can source up to 50mA.
9 OD input Active-low output disable input that disables both outputs; absolute maximum is -0.3V to 38V to GND.
10 VIN2 power_in Input voltage supply for buffer amplifier 2 that should be bypassed with a 0.1µF capacitor to ground; VIN, VIN1, VIN2 absolute maximum is 38V to GND.
11 VIN1 power_in Input voltage supply for buffer amplifier 1 that should be bypassed with a 0.1µF capacitor to ground; VIN, VIN1, VIN2 absolute maximum is 38V to GND.
12 VOUT1_F power_out VOUT1 output that requires a 1µF to 50µF output capacitor for stable operation and can source up to 150mA.
13 VOUT1_S input VOUT1 Kelvin sense pin that should be connected directly to the load.
14 VIN power_in Main input voltage supply that should be bypassed with a 0.1µF capacitor to ground; absolute maximum is 38V to GND.
15 NC unconnected No connect pin.
16 DNC unconnected Do not connect; connected internally, so keep leakage current from this pin to a minimum and do not connect external circuitry to it.
17 GND power_in Exposed pad that is ground and must be soldered to the PCB for good electrical contact and rated thermal performance.
