LD8116DGL from Leadtrend Tech, in a SOT-26. 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 | Supply voltage pin. Recommended operating range 15V to 56V (absolute max -0.3V to 60V). Requires a 0.1uF-0.47uF SMD ceramic bypass capacitor close to the pin. UVLO_ON typ 7.0V, UVLO_OFF typ 6.0V. Operating current typ 600uA. |
| 2 | GND | power_in | Ground or power return pin. |
| 3 | OUT | output | Dimming output. Open-drain configuration (typ 1.5kHz output frequency, sink up to 20mA recommended / 30mA absolute max, VOUT_LOW <=200mV @ 2mA). Connect to a power supply via a pull-up resistor, typically driving the DIM input of a downstream LED driver via an opto-coupler. |
| 4 | ISET | passive | Sets bias current of the DIM pin via a resistor RISET connected between this pin and GND. Recommended RISET range 33k to 330k ohm. Open voltage VISET_OPEN typ 2.5V. IDIM/ISET ratio KDIM typ 4; ICLAMP/ISET ratio KCLAMP typ 0.4. Absolute max -0.3V to 6V. |
| 5 | CLAMP | passive | Sets the minimum output clamped duty cycle via a resistor RCLAMP between this pin and GND. Open voltage VCLAMP_OPEN typ 5.0V. RCLAMP options: >=1M or open -> 0% min duty; 300k -> 4%; 150k -> 6%; 0 ohm -> 8%. Absolute max -0.3V to 6V. |
| 6 | DIM | input | Dimming signal input. Accepts three input modes: 0/1V-10V voltage potential, 0.2kHz-10kHz PWM (high level 3.2-13V, low <=1.2V, slew >=3V/us to trigger PWM mode), or 0-100k ohm potentiometer to GND. Open voltage VDIM_OPEN typ 13V; bias current IDIM_100 typ 100uA at RISET=100k. Absolute max -0.3V to 20V. |
