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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Richtek Tech |+| Package | DFN-14-EP(3x4) |+| Category | Power Management (PMIC) |+| Pins | 15 |++## Electrical characteristics++Limits as printed in the datasheet (page.json `metadata.characteristics` carries them as data).++| Parameter | Symbol | Min | Typ | Max | Unit | Conditions | Page |+|---|---|---|---|---|---|---|---|+| Under-Voltage Lockout Rising Threshold | UVLO_R | 1.6 | 1.7 | 1.8 | V | | 5 |+| Under-Voltage Lockout Falling Threshold | UVLO_F | 1.5 | 1.6 | 1.7 | V | | 5 |+| Minimum Input Voltage for Start-Up | | 1.5 | 1.8 | 2 | V | | 5 |+| FB Voltage | VFB | 0.495 | 0.5 | 0.505 | V | Force PWM (RT6154A) | 5 |+| Shutdown Current | ISHDN | | 0.1 | 1 | µA | EN = 0V, PS/SYNC = 0V, PGOOD = 0V | 5 |+| Switching Frequency | fSW | 2.2 | 2.4 | 2.6 | MHz | | 5 |+| Frequency Range for Synchronization | | 2.2 | 2.4 | 2.6 | MHz | | 5 |+| Current Limit | IOC_36 | 3.9 | 5 | 5.8 | A | VIN = VINA = 3.6V | 6 |+| Current Limit | IOC_21 | 1.7 | 2.6 | 3.7 | A | VIN = VINA = 2.1V | 6 |+| Quiescent Current | | | 20 | 40 | µA | Non switching, EN = VINA, SYNC = 0V | 6 |+| Leakage of LX1 and LX2 | ILX1, ILX2 | | | 5 | µA | All Switch Off | 6 |+| EN, PS/SYNC Logic-High Input Voltage | VIH | 1.2 | | | V | | 6 |+| EN, PS/SYNC Logic-Low Input Voltage | VIL | | | 0.4 | V | | 6 |+| PS/SYNC Input Current | | | 0.1 | 1 | µA | | 6 |+| PGOOD Output Low Voltage | | | 0.04 | 0.4 | V | VOUT = 3.3V, IPGOODL = 10µA | 6 |+| PGOOD Output Leakage Current | | | 0.01 | 0.1 | µA | | 6 |+| VIN, VINA to GND | | -0.2 | | 6 | V | | 5 |+| VOUT to GND | | -0.2 | | 6.5 | V | | 5 |+| EN, PS/SYNC to GND | | -0.2 | | 6 | V | Upper limit printed as (PVIN + 0.2V) with 6V max;
