LM5088MH-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 75 V. |
| 2 | EN | input | Enable input: below 0.4 V the regulator is in a low-power state, 0.4 V to 1.2 V selects standby, and above 1.2 V the controller is operational, with a 5-µA pullup if left open. |
| 3 | SS | passive | Soft-start pin charged by an internal 11-µA source through an external capacitor, controls the error amplifier when below the 1.2-V reference, and is held low in standby, VCC UV, and thermal shutdown. |
| 4 | RAMP | passive | An external capacitor between RAMP and GND sets the emulated current-mode ramp slope, with a recommended range of 100 pF to 2000 pF. |
| 5 | RT/SYNC | input | A single resistor to GND sets the oscillator frequency over a recommended 50 kHz to 1 MHz range, and an external higher-frequency sync signal can be coupled through a small capacitor, with the RT resistor still required. |
| 6 | GND | power_in | Ground return for the controller. |
| 7 | COMP | output | Output of the internal error amplifier, where the loop compensation network must be connected between this pin and FB. |
| 8 | FB | input | 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 capacitor pin (LM5088-2 only) that is charged by 50 µA during over-current events, disables HG when it reaches 1.2 V, and resumes operation when it falls below 0.2 V. |
| 11 | CSG | power_in | Current-sense ground serving as the low-side reference for the current sense resistor. |
| 12 | CS | input | Current measurement connection for the re-circulating diode current, sensed through an external sense resistor and internal sample-and-hold at the end of the buck switch off time to provide the emulated ramp DC offset. |
| 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 gate driver, charged from VCC through an internal diode during the buck off-time. |
| 16 | VCC | power_out | Bias regulator output 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, electrically isolated, that must be soldered to the ground plane to reduce thermal resistance. |
