LM25088QMHX-2 from Texas Instruments, in a HTSSOP-16-EP. 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 | VIN | power_in | IC supply voltage with an operating range of 4.5 V to 42 V. |
| 2 | EN | input | Below 0.4 V puts the regulator in a low-power state, 0.4 V to 1.2 V selects standby, and above 1.2 V makes the controller operational, with a 5-µA pullup if the pin is left open. |
| 3 | SS | input | Soft-start pin charged by an internal 11-µA current source to set the start-up rate, and it can be used for voltage tracking with an applied voltage below 1.2 V. |
| 4 | RAMP | passive | An external capacitor from RAMP to GND sets the emulated current ramp slope, with a recommended range of 100 pF to 2000 pF. |
| 5 | RT/SYNC | input | A single resistor to GND programs the oscillator over a recommended range of 50 kHz to 1 MHz, and an external sync signal higher in frequency can be coupled through a small capacitor while the RT resistor remains required. |
| 6 | GND | power_in | Ground return for the controller. |
| 7 | COMP | output | Output of the internal error amplifier, with the loop compensation network connected between this pin and FB. |
| 8 | FB | input | Feedback input to the inverting input of the internal error amplifier, with a regulation threshold of 1.205 V. |
| 9 | OUT | input | Output voltage connection that must be connected directly to the regulated output voltage. |
| 10 | RES | passive | Hiccup mode restart timing pin for the LM25088-2 with an external capacitor, where HG is disabled when RES reaches 1.2 V and operation resumes when RES falls below 0.2 V. |
| 11 | CSG | passive | Low-side reference for the current sense resistor. |
| 12 | CS | input | Current measurement input for the re-circulating diode current, sensed through an external sense resistor at the end of the buck switch off time. |
| 13 | SW | passive | Switching node that connects to the source terminal of the external MOSFET switch. |
| 14 | HG | output | High-side gate drive output that connects to the gate terminal of the external MOSFET switch. |
| 15 | BOOT | passive | Bootstrap capacitor input, with an external capacitor required between BOOT and SW to bias the MOSFET gate driver. |
| 16 | VCC | power_out | Output of the bias regulator that tracks VIN up to 7.8 V typical and requires a 0.1 µF to 10 µF ceramic decoupling capacitor, with an external 8.3 V to 13 V supply optionally applied to reduce internal dissipation. |
| 17 | EP | passive | Exposed pad that is electrically isolated and must be soldered to the ground plane to reduce thermal resistance. |
