PWMOUT
SYMBOL
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 an external dimming FET.
The PWM operates at ~ 310Hz.
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
