MIC2176-2YMM from Microchip Tech, in a MSOP-10. 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 | HSD | input | High-Side MOSFET Drain Connection (Input). Input of the adaptive on-time control circuitry. Operating range 4.5V to 75V (abs max -0.3V to +76V). Requires a 0.1uF ceramic capacitor between HSD and PGND placed close to the IC. |
| 2 | EN | input | Enable (Input). CMOS-compatible logic-level enable; logic high or floating = enable, logic low = shutdown. In off state VDD supply current drops to ~0.7mA. Logic high >=1.2V, logic low <=0.4V (4.5V<VDD<5.5V). Do not connect EN to HSD. |
| 3 | FB | input | Feedback (Input) to the transconductance amplifier of the control loop. Regulated to 0.8V reference (±1% at 0-85°C, ±1.5% over full temp). A resistor divider from VOUT sets the output voltage. FB bias current typ 5nA (max 500nA). |
| 4 | GND | power_in | Signal ground. Ground return for the VDD bias supply and internal control circuitry. Should be routed separately from PGND (power ground) and joined at a single point. |
| 5 | VDD | power_in | VDD Bias input for the internal reference and control sections. Operating range 4.5V to 5.5V. Requires a 1uF ceramic bypass capacitor from VDD to PGND placed next to the IC. Quiescent current ~1.4mA (max 3mA). |
| 6 | DL | output | Low-Side Gate Drive (Output). High-current gate driver for the external low-side N-channel MOSFET. Output swings from GND to VDD. On-resistance typ 1.2Ω (low) / 1.8Ω (high), driver sourcing/sinking 10mA. |
| 7 | PGND | power_in | Power Ground. Ground return path for the buck converter power stage; connects to the sources of the low-side external N-channel MOSFETs, negative terminals of input capacitors, and negative terminals of output capacitors. Route separately from signal GND with a low-impedance loop. |
| 8 | DH | output | High-Side Gate Drive (Output). High-current gate driver for the external high-side N-channel MOSFET, referenced to the SW node (floating). Swings between SW and BST. A small series resistor between DH and the MOSFET gate can slow turn-on/turn-off. On-resistance typ 2.1Ω (high) / 1.8Ω (low). |
| 9 | SW | input | Switch Node and Current-Sense input. High-current output driver return that connects directly to the switch node (drain of low-side MOSFET / source of high-side MOSFET). Also senses inductor current across the low-side MOSFET RDS(on) during OFF time - use a Kelvin connection to the low-side MOSFET drain for accurate sensing. |
| 10 | BST | power_in | Bootstrap (Output). Bootstrapped supply for the high-side N-channel MOSFET gate driver. Connect a Schottky diode from VDD to BST and a 0.1uF boost capacitor from BST to SW. A small series resistor at BST can slow high-side MOSFET turn-on. Abs max -0.3V to (VSW+6V), -0.3V to +82V vs PGND. |
