Kiwi Instruments · DC-DC Converters · TSOT-23-6

KP523208ALGA from Kiwi Instruments, in a TSOT-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 GND power_in Power and signal ground for the converter; the datasheet gives no voltage limit for this pin.
2 SW power_out Switching node that must be connected to the output inductor with a short, wide trace; the SW pin voltage limits are DC -0.1 V to 17 V and transient (<10 ns) -3 V to 19 V under recommended conditions.
3 VIN power_in Input supply pin with a 4.5 V to 17 V recommended range; place a 100 nF ceramic decoupling capacitor as close as possible to the VIN and GND pins.
4 FB input Feedback pin that receives the resistor-divided output voltage to set and regulate VOUT, with a reference of 0.768 V and a recommended EN/FB range of -0.1 V to 5.5 V.
5 EN input Enable control pin that is pulled high or left floating to enable operation; when tied to VIN a series pull-up of at least 100 kΩ is required, and it can also set the VIN UVLO thresholds.
6 BST power_out Charge-pump voltage that drives the high-side MOSFET; connect a 100 nF ceramic capacitor between BST and SW, with a recommended BST range of -0.1 V to 22.5 V and BST-SW of -0.1 V to 5.5 V.
