LP6261B6F

LOWPOWER · DC-DC Converters · SOT-23-6

LP6261B6F from LOWPOWER, in a SOT-23-6. 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 VOUT power_out Voltage output pin of the boost converter; the datasheet gives VOUT to GND as an absolute maximum of 8V.
2 GND power_in Ground pin; the datasheet gives VIN and EN to GND, VOUT to GND and SW to GND absolute maximum ratings of 6.5V, 8V and 10V respectively.
3 EN input Chip enable: logic high enables the device and logic low disables it, with EN input low at 0.3V max and high at 1.4V min, and it must not be left floating.
4 VIN power_in Voltage supply input pin; VIN to GND absolute maximum is 6.5V.
5 NC unconnected No connect on the LP6261 (B6F, fixed 5.1V) variant; this pin is the FB feedback pin (feedback voltage 1.36V) only on the LP6261A (AB6F) variant.
6 SW output Switching pin of the boost converter; SW to GND absolute maximum is 10V.
