HX1002-GEC from HEXIN, in a SOT-23-5L. 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 | Main supply input, 3.4V to 5.5V for the -GE 3.3V fixed-output variant (absolute max -0.3V to +6V). Requires a 10μF ceramic decoupling capacitor closely coupled to GND. |
| 2 | GND | power_in | Device ground reference. Return path for the input capacitor and internal power switches; connect analog and power grounds at a common node. |
| 3 | EN | input | ON/OFF control, active-high. Above 1.3V enables the part; below 0.7V shuts it down (<1μA shutdown supply current). Absolute max -0.3V to (VIN+0.3)V. Do not leave floating. |
| 4 | VOUT/FB | input | Output-sense/feedback pin. On the fixed-output HX1002-GE variant this pin senses the internally-regulated 3.3V VOUT directly (connect to the output rail). On adjustable variants it is the FB input with VFB=0.605V and a resistive divider setting VOUT = 0.605V·[1+(R1/R2)]. Absolute max -0.3V to +6V; typical feedback current ±30nA. |
| 5 | SW | output | Switch node - connects internally to the drains of the P-channel main and N-channel synchronous power MOSFETs. Drives the external inductor (typ. 4.7μH). Peak switch current ~0.9A typ, 1.3A absolute max; RDS(ON) 0.3Ω (PFET) / 0.39Ω (NFET). High-dv/dt node - keep trace area small. |
