CR5218SC

Chip-Rail · AC-DC Controllers & Regulators · SOP-8

CR5218SC from Chip-Rail, 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 CS input Current-sense pin for the external CS resistor used for primary peak current detection (input range -1 to 5 V, OCP threshold 500 mV typ, 300 ns LEB).
2 GND power_in Ground pin.
3 FB input Primary-side voltage feedback pin (input range -0.3 to 6 V, 1.2 V typ reference threshold, 0.5 V short-protection threshold).
4 VCC power_in IC supply pin providing voltage for normal operation (recommended 3.5 to 5 V, 5.2 V typ clamp at 2 mA).
5 C passive High-voltage collector terminal of the integrated power BJT (850 V VCBO for CR5218SC, 0.8 A collector current rating), tied with pins 6, 7 and 8.
6 C passive High-voltage collector terminal of the integrated power BJT (850 V VCBO for CR5218SC, 0.8 A collector current rating), tied with pins 5, 7 and 8.
7 C passive High-voltage collector terminal of the integrated power BJT (850 V VCBO for CR5218SC, 0.8 A collector current rating), tied with pins 5, 6 and 8.
8 C passive High-voltage collector terminal of the integrated power BJT (850 V VCBO for CR5218SC, 0.8 A collector current rating), tied with pins 5, 6 and 7.
