The TPS92200 device supports flexible dimming
methods. TPS92200D1 implements both PWM and
analog dimming modes. In PWM dimming mode,
LEDs turn on and off according to PWM duty cycle
periodically. The device's analog dimming mode is
achieved by changing the internal reference voltage
proportional to the voltage level of the analog input in
5% to 100% range. TPS92200D2 implements deeper
analog dimming by changing the internal reference
voltage proportional to the duty cycle of the PWM
signal input in 1% to 100% range.
