ME8311AS7G

MICRONE · AC-DC Controllers and Regulators · SOP-7

ME8311AS7G from MICRONE, in a SOP-7. 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 VDD power_in Chip power supply, typically fed from the transformer auxiliary winding via a rectifier. UVLO(off)=13.5V typ (start-up), UVLO(on)=8.0V typ, VDD_OVP=31V typ, max operating voltage 30V, absolute max 30V. Static current ~420µA at 15V; start-up current ~1µA at 11V.
2 COMP passive Loop compensation node for the CV control loop. An external compensation capacitor (Cc) is connected from this pin to GND to set the CV loop stability.
3 INV input Voltage feedback input from the auxiliary winding via an external resistor divider (R1/R2). The auxiliary voltage is sampled mid-demagnetization and compared to VREF_INV = 2.00V typ (1.94-2.10V). Used to reflect the output voltage; PWM duty cycle is derived from the EA output and the CS current-sense signal. Absolute max -0.3 to +7V.
4 CS input Current-sense input. Connected to the source-side sense resistor (Rs) of the internal power MOSFET; sets the OCP / CC point. Over-current threshold Vth_ocp = 500mV typ (485-515mV), LEB time ~0.5µs, OCP propagation delay ~100ns. Absolute max -0.3 to +7V.
5 DRAIN power_out Drain of the integrated 600V high-voltage power MOSFET. Connects to the primary winding of the flyback transformer. Pins 5 and 6 are internally tied together for improved current handling and thermal dissipation. Static Rds(on) ~10Ω typ (15Ω max) at Vgs=10V, Id=1A; BVdss ≥ 600V.
6 DRAIN power_out Drain of the integrated 600V high-voltage power MOSFET (second bond of the same internal net). Connects to the primary winding of the flyback transformer along with pin 5.
7 GND power_in Device ground / source return for the integrated power MOSFET and reference for all analog signals. On the SOP-7 variant, GND appears on pin 7 only (the SOP-8 splits GND across pins 7 and 8).
