PIN | TYPE(1) | DESCRIPTION | |
---|---|---|---|
No. | NAME | ||
1 | PGND | G | Power ground pin. |
2 | AGND | G | Analog ground pin. |
3 | VIN | P | Input power pin. |
4 | VCC | P | Internal LDO output pin. Connect with a 10-V, 1-uF capacitor to GND. |
5 | ADIM/HD | I | Analog dimming or hybrid dimming pin. Pull high for PWM dimming only, pull low for hybrid dimming, input PWM signal for analog dimming. |
6 | PWM/EN | I | PWM dimming or EN pin. Pull high for always on, pull low for disabling the device, input PWM signal for PWM dimming. |
7 | FAULT | O | Open drain output. Pull low when fault is detected. |
8 | TEMP | I/O | Thermal foldback pin. Put different resistor values to GND to set different thermal foldback behavior curves. |
9 | FSET | I/O | Switching frequency set pin, with range of 100 kHz ~ 2.2 MHz. Put different resistor values to GND for different switching frequencies. |
10 | COMP | I/O | Error-amilifier output. Connect capacitors to GND. Different capacitor values determine different softstart times and bandwidths. |
11 | UVP | I | Undervoltage detection pin. Put different resistor dividers to set the LED open detection thresholds. |
12 | CSP | I | LED current sense positive pin. |
13 | CSN | I | LED current sense negative pin. |
14 | SW | P | Switching node pin. Internally connected to the low-side MOSFET. Connect with the power inductor and the schottky diode. |
Pad | Thermal Pad | G | Power ground pin. |
