MT7860 from MAXIC Tech, in a SOP-8. 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 | Supply pin. Recommended operating range 9V to 28V. Startup threshold VSTP = 14V, UVLO = 9V, internal Zener clamp OVP1 = 28V with 5mA clamp capability. Startup current ISTP = 25uA at VDD=16V, quiescent current IQ = 1.0mA. |
| 2 | PWM | input | PWM dimming signal input pin. The duty cycle of the applied PWM signal is decoded to set LED current: 20% duty = zero LED current, 80% duty = maximum LED current. Absolute maximum -0.3V to 5V. |
| 3 | CLPF | input | Analog dimming signal input pin / PWM dimming signal low-pass filter capacitor. Absolute maximum -0.3V to 5V. |
| 4 | COMP | output | Internal error-amplifier output. Connect a capacitor to GND for loop frequency compensation. Pre-charged during startup; system enters normal operation once COMP reaches 1.4V. Absolute maximum -0.3V to 5V. |
| 5 | CS | input | Current-sense input from the source resistor of the external power MOSFET. Cycle-by-cycle over-current threshold OCP = 1.4V with 300ns leading-edge blanking (LEB2). Absolute maximum -0.3V to 5V. |
| 6 | DSEN | input | Feedback/demagnetization sense pin. Connected through a resistor divider to the LED output or auxiliary winding. Reference voltage VFB = 200mV (196-204mV). SCP threshold 400mV, OVP2 threshold 3.2V, LEB1 = 2us. Absolute maximum -0.3V to 5V. |
| 7 | GND | power_in | Ground reference for the IC. |
| 8 | DRV | output | Gate-drive output for the external power MOSFET. Max sink current 2A, max source current 1A. Absolute maximum -0.3V to VDD. |
