MCP16301HT-E

Microchip · DC-DC Converters · SOT-23-6

MCP16301HT-E from Microchip, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BOOST passive Boost pin for the internal high-side NMOS gate driver's floating supply. An external bootstrap capacitor (typ. 100 nF) is connected between BOOST and SW; charge is refreshed from VOUT through an external boost diode (e.g. 1N4148). Absolute max BOOST-GND = -0.5V to 46V; BOOST-SW = -0.5V to 6.0V.
2 GND power_in Device ground and return pin for all internal circuitry. Should form a short, low-impedance path back to the input capacitor, output capacitor return, and Schottky freewheel diode to minimize switching noise.
3 VFB input Output-voltage feedback pin. Connect the midpoint of an external resistor divider from VOUT to GND here; the internal error amplifier regulates VFB to VREF = 0.800V typ. (0.784V-0.816V). Feedback input bias current is ±10 nA typ. (±250 nA max). Absolute max = -0.5V to 6.0V.
4 EN input Active-high enable input. VIH ≥ 1.4V turns the regulator on; VIL ≤ 0.4V forces shutdown (IQ ≈ 7 µA). Do not float. Input leakage 0.05 µA typ (1.0 µA max) at VEN = 12V. Absolute max = -0.5V to (VIN + 0.3V).
5 VIN power_in Input supply for the power stage and internal bias. Operating range 4.7V-36V (MCP16301H) or 4.0V-30V (MCP16301). Requires a 4.7-20 µF ceramic bypass to GND close to the pin (1 µF X7R/X5R acceptable for light loads, -40 to +85°C). UVLO start typ. 3.5V, stop typ. 3.0V.
6 SW output Switch node: drain of the internal 460 mΩ high-side N-channel MOSFET. Connects to the external inductor, the freewheel Schottky diode cathode, and the bootstrap capacitor lower plate. Current-limited at 1.3A typ. Absolute max VIN-SW = -0.5V to 40V; slews very fast, keep the Schottky close to SW and GND.

  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: mcp16301ht-e-etched.step / mcp16301ht-e-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mcp16301ht-e.step / mcp16301ht-e.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mcp16301ht-e.step 97 KB You want the bare part, or you mark your own boards.
mcp16301ht-e-etched.step 2.0 MB You want the part with MCP16301HT-E already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 503 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
