The ROHM 2 channel synchronous buck DC/DC LED driver utilizes an on time topology, supporting a near fixed switching frequency and fast switching duty regulation. It employs an average LED current feedback buck topology for precise LED current regulation across a wide input and LED output range. This driver supports individual 10 bit analogue dimming and 10 bit PWM dimming, programmable via a 10 bit register through SPI.
