Overview
AOZ1950 Boost Regulator White LED Driver General Description The AOZ1950 is a high-efficiency boost regulator with internal 60V MOSFET and input protection switch.
The part is designed to drive up to twelve white LEDs in series.
The AOZ1950 supports two dimming control methods: analog dimming and PWM dimming.
In analog dimming mode, the LED current can be linearly adjusted for ±12% with a DC voltage on DIM pin.
In PWM dimming mode, the LEDs can be turned on and off by toggling EN pin with a square wave, and the brightness is proportional to the duty cycle of the control signal.
AOZ1950 is a fixed OFF pulse regulator with adaptive pulse width as a function of input and output voltage.
