RT9288A controller equivalent, pwm step-up dc/dc controller.
z VIN Operating Range : 3V to 13.5V z Fixed PWM Frequency : 1MHz z 200Hz to 200kHz PWM Dimming Frequency z Flexible PWM/Analog Dimming Control z Voltage Mode with Externa.
Adjusting the output current of the RT9288A changes the brightness of the WLEDs. Chip Enable pin can be used as a digit.
The RT9288A is a wide input operating voltage range stepup controller. High voltage output and large output current are feasible by using an external N-MOSFET. The RT9288A input operating range is from 3V to 13.5V. Besides, it could support up to 60V.
