MIC38HC43YM

Microchip Tech · DC-DC Converters · SOIC-8

MIC38HC43YM from Microchip Tech, in a SOIC-8. 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 COMP output Error amplifier output where the external compensation network is connected.
2 FB input Error amplifier feedback input, regulated to 2.5V at the desired output voltage, with absolute maximum range of -0.3V to 5.5V.
3 ISNS input Current sense comparator input connected to a current sensing resistor or current transformer, with absolute maximum range of -0.3V to 5.5V.
4 RT/CT passive Timing resistor/timing capacitor connection; the external RC network sets the switching frequency.
5 GND power_in Combined analog and power ground.
6 OUT output Totem-pole power output with rail-to-rail swing and 1A peak output current.
7 VDD power_in Controller and output stage supply input, 20V maximum, with MIC38HC43 UVLO start threshold 8.4V typical and minimum operating voltage 7.6V typical.
8 VREF power_out 5V trimmed reference output (4.90V to 5.10V at 25°C, 1mA) with an external RC network connected.

CAD (KiCad official)

  • Symbol: MIC38HC43YM
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: mic38hc43ym-etched.step / mic38hc43ym-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mic38hc43ym.step / mic38hc43ym.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Microchip Tech datasheet (8 pp, sha256 cc00f3b9dcbc79e3, retrieved 2026-10-31, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
