TM5880

TM Shenzhen Titan Micro Elec · AC-DC Controllers And Regulators · SOT-23-6

TM5880 from TM Shenzhen Titan Micro Elec, in a SOT-23-6. 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 GND power_in Chip ground reference for the controller; all voltages are specified relative to system ground.
2 GATE output Drives the external power MOSFET with a soft-drive output clamped internally at 16 V (VOH 7.5 V min at 20 mA source, VOL 1 V at 20 mA sink), with GATE voltage rated to 20 V absolute maximum.
3 CS input Samples the primary-side current through an external sense resistor for cycle-by-cycle current limit, with 500 ns leading-edge blanking, and is rated -0.3 V to 7 V.
4 CC passive Connects an external capacitor used for constant-current regulation, referenced to an internal 500 mV (490-510 mV) CC reference; CC voltage is rated -0.3 V to 7 V.
5 FB input Output voltage feedback input with a 2.0 V reference (1.98-2.02 V), output over-voltage threshold 2.4 V, output short/under-voltage threshold 0.65 V, and absolute range -0.7 V to 7 V.
6 VDD power_in Controller supply pin with recommended operating range 10-30 V, UVLO off/on at 9.5 V / 15.5 V typical, over-voltage protection at 33 V typical, and clamp at 35 V typical; absolute maximum 35 V.
