HT2451ARTZ

HTCSEMI · DC-DC Converters · SOT-23-6

HT2451ARTZ from HTCSEMI, 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 BST power_out Bootstrap pin and positive supply for the internal floating high-side MOSFET driver; a bypass capacitor is connected between this pin and SW, and the bootstrap capacitor is held at about 5 V with the floating driver UVLO at about 2.4 V.
2 GND power_in Ground pin, to be connected as close as possible to the output capacitor and kept away from the high-current switching path.
3 FB input Feedback input to the error amplifier; an external divider from output to ground is compared with the internal +0.8 V reference (Vfb 0.778 V to 0.810 V for 4.0 V < Vin < 36 V) to set the regulated output.
4 EN input Enable input: pulling it below the specified threshold shuts the chip down, pulling it above the threshold enables operation, and leaving it floating disables the chip (EN high threshold 1.4 V min, 1.55 V typ, 1.7 V max).
5 VIN power_in Power input supplying all internal control circuits including the power switch, requiring a decoupling capacitor to ground to reduce switching spikes; operating input range is 3.3 V to 36 V.
6 SW output High-side switch output; a low-VF Schottky diode to ground should be placed close to this pin to reduce switching spikes.
