PAM2305CGFADJ

Diodes Incorporated · DC-DC Converters · DFN-6-EP(2x2)

PAM2305CGFADJ from Diodes Incorporated, in a DFN-6-EP(2x2). 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 NC unconnected No connection on the DFN2x2-6L package; this pin is not connected internally.
2 EN input Enable control input: a voltage above 1.5V enables the chip and a voltage below 0.3V shuts down the device.
3 VIN power_in Chip main power supply pin, specified for 2.5V to 5.5V operation with an absolute maximum rating of -0.3V to +6.0V.
4 SW output Drains of the internal main and synchronous power MOSFETs; the SW pin voltage is rated -0.3V to (VIN + 0.3)V.
5 GND power_in Ground reference pin for the device.
6 VOUT/FB input Output voltage feedback pin, which uses an internal resistive divider on the fixed-output versions, or the feedback input to the internal error amplifier with a 0.6V threshold on the adjustable (ADJ) version such as PAM2305CGFADJ, with FB rated -0.3V to VIN.
7 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
