GR9230RKKAG

Grenergy · AC-DC Controllers & Regulators · SOP-7

GR9230RKKAG from Grenergy, 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 VCC power_in IC power supply pin. UVLO-ON ≈16.0 V, UVLO-OFF ≈7.5 V, VCC OVP ≈28 V, max 30 V. Bypass with a 2.2-10 µF electrolytic plus a 0.1-0.47 µF SMD ceramic capacitor placed close to the pin.
2 COMP input Voltage feedback / compensation pin. A photocoupler connected here sinks current to control the primary-side duty cycle. Open-loop voltage ~5.2 V, short-circuit current ~230 µA, green-mode threshold ~1.35 V. Bypass with a 1-33 nF capacitor to GND.
3 QRD input Quasi-resonant (valley) detection and OVP sense pin. Driven from an auxiliary winding through a divider; internal clamps at +4.6 V / -0.3 V, QRD-OVP trip ≈3.5 V (128 µs debounce), UVP level 0.5 V (8 ms de-bounce after start-up). Requires a 4.7-33 pF filter capacitor to GND.
4 CS input Current-sense input from the source-side sense resistor. Peak-current threshold VCSmax ≈0.85 V (low line) / 0.7 V (high line), OCP comparator reference 0.85 V, leading-edge blanking 350 ns, input impedance 1 MΩ, delay-to-output 100 ns.
5 DRAIN power_in Drain of the internal 650 V high-voltage power MOSFET. Pin 5 is tied internally to the same DRAIN node as pin 6 for improved current handling and heat spreading. Connects to the transformer primary winding.
6 DRAIN power_in Drain of the internal 650 V high-voltage power MOSFET (paralleled with pin 5). Connects to the transformer primary winding.
7 GND power_in Ground reference pin for the controller and the source of the internal high-voltage MOSFET. All bypass capacitors and the CS-sense resistor return here.
