CL1652A

ChipLink Tech · DC-DC Converters · SOT-23-5

CL1652A from ChipLink Tech, in a SOT-23-5. 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	EN	input	Enable control, active high; it must not be left floating, and pulling it below 0.4V shuts the device down while above 1.5V re-enables it.
2	GND	power_in	Ground pin.
3	SW	output	Inductor pin; connect to the switching node of the inductor.
4	IN	power_in	Power supply input, operating from 2.7V to 5.5V.
5	FB	input	Output feedback pin; connect to the midpoint of the output divider to set the output voltage, Vout = 0.6 × (1 + R1/R2).
