ZXLD1360-MS

MSKSEMI · LED Drivers · SOT-23-5

ZXLD1360-MS from MSKSEMI, in a SOT-23-5. 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 SW bidirectional Drain of the internal power MOS switch (SW pin), rated at a maximum SW current of 1.0 A and covered by the 35 V maximum pin voltage limit (RDS(on) 300 mΩ at VIN 6 V to 30 V).
2 GND power_in Chip ground reference for the device.
3 DIM input Brightness control input supporting PWM and analog dimming: DIM below 0.3 V turns the output off into standby, DIM high (VIH 2.0 V min) enables switching, and the pin is limited to 6 V maximum; leave floating if dimming is not used (about 5 V on the pin).
4 CS input Current-sense input for the high-side sense resistor; the sense threshold is VIN-VCS = 100 mV typical (95 to 105 mV), with a CS pin input current of 10 µA.
5 VIN power_in Supply input with an operating range of 5.5 V to 30 V, a 35 V maximum pin voltage limit, and a 5.1 V undervoltage lockout threshold; it needs a 22 to 47 µF filter capacitor rated above the maximum input voltage.
