ME2199ASG from MICRONE, in a SOP-8. 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 | VSENSE | input | Current-sense resistor connection. The internal current-limit comparator trips when V(VSENSE) reaches the 100mV (typ, 92-114mV) reference; in constant-current mode the output current is set by RSENSE = 0.1V / IOUT. |
| 2 | FB | input | Voltage feedback input to the error amplifier. Regulates to VFB = 1.25V (±2%, 1.225-1.275V); output voltage set by VOUT = 1.25V × (1 + RFB1/RFB2). Input bias current ±0.1µA. |
| 3 | VDD | power_in | Chip supply pin, powered from an internal LDO fed by VIN. Bypass with a 1µF ceramic capacitor to GND. Absolute max 5.5V. |
| 4 | NC | unconnected | No connect. Leave floating or tie to GND per board practice. |
| 5 | GND | power_in | Device ground reference for the analog control circuitry and the external MOSFET gate driver return. |
| 6 | VIN | input | Over-voltage protection / VIN feedback sense pin, connected to the boost-output side for OVP feedback (not the main power supply - that enters via the internal LDO from this same rail sense). Absolute max 5.5V on this feedback path; the boost input rail itself supports 2.7-25V. |
| 7 | EXT | output | External power-MOSFET gate driver output. Drives the gate of the external N-channel switch at up to ~1MHz with PWM/PFM modulation and internal ramp/phase compensation. |
| 8 | CE | input | Chip enable / shutdown control. VIH ≥ 0.75V enables the device; VIL ≤ 0.3V puts it in shutdown (ISSS ≤ 5µA at VEN = 0V). Input leakage ±0.1µA. |
