PWMOUT
SYMBOL
PART NUMBER
(Notes 1, 2, 3)
OUT
The PWM gate drive output for LED dimming. The output level is clamped to ~12V for VDD greater than 12V. PWMOUT has pull-
down capability when UVLO is active or when the IC is not biased. This output is used to drive the dimming FET in series with the
LED string. The PWM operates at ~ 320Hz.
The gate drive output for the external power FET. OUT is capable of sourcing and sinking 1A @ VDD = 8V. The output level is clamped
to ~12V for VDD greater than 12V. OUT has pull-down capability when UVLO is active or when the IC is not biased.
Isolated and non-isolated single-stage flyback regulator.
Isolated and non-isolated single-stage flyback regulator with inrush control and interface features for temperature and
ambient light sensors.
Non-isolated single-stage buck regulator using switch current for regulation.
Isolated single-stage flyback regulator with primary side current sense regulation.
Non-isolated two-stage cascaded boost PFC + buck regulator eliminates dependency on electrolytic capacitors.
Isolated two-stage cascaded boost PFC + flyback regulator eliminates dependency on electrolytic capacitors.
