GBI5132QYAR from GOSEMICON, in a QFN-20-EP(3.5x3.5). 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 | OUT | power_out | Regulated output pin; a 22µF or larger capacitor (10µF or greater effective capacitance) is required for stability and should be placed as close to the device as possible. |
| 2 | SNS | input | Output voltage sense pin, connected only when setting OUT by PCB layout with no external resistor; keep floating when OUT is set by an external resistor divider. |
| 3 | FB | input | Feedback pin to the error amplifier; a 10nF feed-forward capacitor between FB and OUT is recommended, though it may disrupt Power-Good (PG) functionality. |
| 4 | PG | output | Open-drain power-good output that is active high when the output is above 91% of target and pulled low below 85% of target, during EN shutdown, OTP, or OCP. |
| 5 | 25mV | input | Voltage-setting pin for the internal feedback network; connect to GND or SNS to select the output voltage, or leave floating when not in use. |
| 6 | 50mV | input | Voltage-setting pin for the internal feedback network; connect to GND or SNS to select the output voltage, or leave floating when not in use. |
| 7 | 100mV | input | Voltage-setting pin for the internal feedback network; connect to GND or SNS to select the output voltage, or leave floating when not in use. |
| 8 | GND | power_in | Ground pin that must be connected to ground, the thermal pad, and the other GND pins with a low-impedance connection. |
| 9 | 200mV | input | Voltage-setting pin for the internal feedback network; connect to GND or SNS to select the output voltage, or leave floating when not in use. |
| 10 | 400mV | input | Voltage-setting pin for the internal feedback network; connect to GND or SNS to select the output voltage, or leave floating when not in use. |
| 11 | 800mV | input | Voltage-setting pin for the internal feedback network; connect to GND or SNS to select the output voltage, or leave floating when not in use. |
| 12 | BIAS | input | BIAS supply pin that enables low-input, low-output (LILO) operation; a 1µF capacitor (0.47µF or larger) must be connected to ground, and the pin may be left floating or tied to ground if unused. |
| 13 | NR/SS | bidirectional | Noise-reduction and soft-start pin; an external capacitor to ground reduces reference noise and enables soft-start, with 10nF or larger recommended as close to the pin as possible. |
| 14 | EN | input | Enable pin; logic high enables the device and logic low disables it, and it must be tied to IN or BIAS if enable functionality is not required. |
| 15 | IN | power_in | Input supply voltage pin; a 10µF or larger ceramic capacitor (5µF or greater effective) from IN to ground is required, placed as close as possible to the input. |
| 16 | IN | power_in | Input supply voltage pin; a 10µF or larger ceramic capacitor (5µF or greater effective) from IN to ground is required, placed as close as possible to the input. |
| 17 | IN | power_in | Input supply voltage pin; a 10µF or larger ceramic capacitor (5µF or greater effective) from IN to ground is required, placed as close as possible to the input. |
| 18 | GND | power_in | Ground pin that must be connected to ground, the thermal pad, and the other GND pins with a low-impedance connection. |
| 19 | OUT | power_out | Regulated output pin; a 22µF or larger capacitor (10µF or greater effective capacitance) is required for stability and should be placed as close to the device as possible. |
| 20 | OUT | power_out | Regulated output pin; a 22µF or larger capacitor (10µF or greater effective capacitance) is required for stability and should be placed as close to the device as possible. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
