Pin Name
Switching Frequency selection pin.
In case of 70kHz,connect RT pin to
REFOUT pin.
on time
Built-in 3V Regulate out Pin.
External LED current Limit Setting pin. If less
than VREF (0.61V) voltage is input, Peak current
value is used at the input voltage. If more than
REF_IN voltage is input, it is done at VREF
voltage. If this function isn’t used, please connect
nothing.
LED current sensing in. If this terminal voltage
exceeds VREF (Or REF_IN), external FET is
OFF. And if the voltage of the terminal exceeds
1.9V, LV5026M turns to latch-off mode.
PWM Dimming pin.L or open: normal operation,
H: Stop operation.
GND pin.
Driving the external FET Gate Pin.
Power supply pin. Operation
This pin drive the FET which is stabilized the
TRIAC dimming application.
If ACS is less than 3V, OUT2 turn High voltage.
ACS pin senses AC Voltage.
: VIN＞UVLOONStop: VIN＜UVLOOFF
L or Open : 50kHz Switching,
H: 70 kHz Switching.
If this function isn’t used, please connect to
nothing.
Switching Stop : VIN>VINOVP
If this function isn’t used, please connect
nothing.
If this function isn’t used, please connect GND.
