Maximum power draw on Pi Pico 3.3V rail with USB power

The Pi Pico datasheet recommends a maximum power draw on the 3V3 pin (pin 36) of 300mA. However, the RT6154B datasheet indicates that up to 3A can be drawn when Vin > 3.6V, which is the case when powering the Pico from the USB connector with a 5V/3A…

Pi Pico W: what is the practical difference between RUN and 3V3_EN pins?

Pi Pico W datasheet states: 3V3_EN connects to the on-board SMPS enable pin, and is pulled high (to VSYS) via a 100kΩ resistor. To disable the 3.3V (which also de-powers the RP2040), short this pin low. and RUN is the RP2040 enable pin, and has…
