RT6154AGQW

Richtek Tech · DC-DC Converters · DFN-14-EP(3x4)

RT6154AGQW from Richtek Tech, in a DFN-14-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 VINA power_in Supply voltage input, recommended 1.8V to 5.5V, with absolute maximum rating of −0.2V to 6V to GND.
2 GND power_in Analog ground.
3 FB input Voltage feedback of the adjustable version (RT6154A), with a typical regulated value of 500mV; must be connected to VOUT on the fixed 3.3V version (RT6154B).
4 VOUT power_out Buck-boost converter output, adjustable from 1.8V to 5.5V on the RT6154A and fixed at 3.3V on the RT6154B; absolute maximum −0.2V to 6.5V to GND.
5 VOUT power_out Buck-boost converter output (second VOUT pin, same net as pin 4); absolute maximum −0.2V to 6.5V to GND.
6 LX2 passive Second switch node; the buck-boost inductor is connected between LX1 and LX2, with LX2 limited to (PGND − 0.2V) to (PVIN + 0.2V) and 6.5V max.
7 LX2 passive Second switch node (second LX2 pin, same net as pin 6); the inductor is connected between LX1 and LX2.
8 LX1 passive First switch node; the buck-boost inductor is connected between LX1 and LX2, with LX1 limited to (PGND − 0.2V) to (PVIN + 0.2V) and 6V max.
9 LX1 passive First switch node (second LX1 pin, same net as pin 8); the inductor is connected between LX1 and LX2.
10 VIN power_in Power input, recommended 1.8V to 5.5V, with absolute maximum rating of −0.2V to 6V to GND.
11 VIN power_in Power input (second VIN pin, same net as pin 10).
12 EN input Enable control input (1 enabled, 0 disabled) that must not be left open; logic-high minimum 1.2V and logic-low maximum 0.4V.
13 PS/SYNC input Enable/disable control for power save mode (1 disabled, 0 enabled) and clock input for synchronization from 2.2MHz to 2.6MHz; must not be left open.
14 PGOOD output Power good indicator output (1 good, 0 failure), open-drain so it requires a pull-up to the logic supply; low output voltage 0.4V max.
15 PGND power_in Exposed pad, power ground; the exposed pad must be soldered to a large PCB and connected to PGND for maximum power dissipation.
