LM25088MHX-1 from Texas Instruments, in a HTSSOP-16-EP. 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 | VIN | power_in | Input supply voltage; IC operating range 4.5 V to 42 V. |
| 2 | EN | input | Enable input; below 0.4 V is shutdown mode, 0.4 V to 1.2 V is standby mode, above 1.2 V is operational. |
| 3 | SS | input | Soft-start input; internal 11-µA current source charges external capacitor to control startup ramp. |
| 4 | RAMP | output | Ramp signal output; external capacitor between this pin and GND sets emulated current mode control slope. |
| 5 | RT/SYNC | input | Oscillator frequency setting input (single resistor to GND sets 50 kHz to 1 MHz) and external synchronization input. |
| 6 | GND | power_in | Ground return. |
| 7 | COMP | output | Error amplifier output; loop compensation network connected between this pin and FB pin. |
| 8 | FB | input | Feedback input; connected to error amplifier inverting input with 1.205 V regulation threshold. |
| 9 | OUT | input | Output voltage sense input; connect directly to regulated converter output. |
| 10 | DITH | output | Frequency dithering output (LM25088-1 only); capacitor to GND modulates oscillator frequency ±5% from nominal set by RT resistor. |
| 11 | CSG | power_in | Current sense ground; low-side reference for external current sense resistor. |
| 12 | CS | input | Current sense input; measures re-circulating diode current for emulated ramp DC offset level. |
| 13 | SW | output | Switching node output; connected to source terminal of external high-side MOSFET switch. |
| 14 | HG | output | High-side gate driver output; connected to gate terminal of external MOSFET. |
| 15 | BOOT | power_out | Bootstrap capacitor connection; external capacitor between BOOT and SW pins charged from VCC to bias gate driver. |
| 16 | VCC | power_out | Bias regulator output; regulated to 7.8 V typical, requires 0.1 µF to 10 µF ceramic decoupling capacitor. |
| 17 | EP | passive | Exposed pad; electrically isolated, must be soldered to ground plane to reduce thermal resistance. |
