EG1252L from EG Micro, in a SOP-8. 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 | FB | input | Feedback input: the PWM duty cycle is set by this pin's voltage together with the current-sense signal, with FB open-circuit voltage 5.3 V (typ.) and FB-to-GND short-circuit current 1.2 mA (typ.). |
| 2 | BO | input | Input voltage detection pin for input undervoltage protection, with a protection voltage VBO of 0.95 V and an internal 9 µA pull-down current source active when VBO is below 0.9 V. |
| 3 | CS | input | Current-sense input that reads the voltage across the external sense resistor for cycle-by-cycle overcurrent limiting, with Vcs(max) of 0.92 V min, 1 V typ and 1.08 V max and 250 ns leading-edge blanking. |
| 4 | RI | passive | Frequency-setting pin: an external resistor from RI to GND sets the switching frequency per Fosc(kHz) = 4200 / RI(kΩ), with an RI open-circuit voltage of 2 V. |
| 5 | GND | power_in | Chip ground. |
| 6 | OUT | output | Gate drive output for the power MOSFET, with a maximum of VCC + 0.3 V, a high-level output of 13 V (typ.) at 20 mA source and a low-level output of 0.3 V at 20 mA sink. |
| 7 | VCC | power_in | Supply pin with a 30 V absolute maximum, a 32 V (typ.) zener clamp at 10 mA, and 2.3 mA (typ.) operating current. |
| 8 | RT | input | Over-temperature protection pin: an external NTC thermistor sets the trip point, with an 80 µA internal current source flowing out of RT, protection entering at 1 V and releasing above 1.1 V. |
