Preliminary RT9273 High Performance, OLED + LED Driver for Dual Panel Mobile Phone General Description The RT9273 is a high efficiency step-up DC-DC converter specifically designed for dual panel mobile phone applications.
According to SP status, RT9273 can either regulates output current flowing through series-connected LEDs or regulate output voltage applying to OLED with a common output LC filter.
This along with compact VDFN-10L 3x3 package and high switching frequency allows less part count and smaller external components for space and cost saving.
Pulling low EN pin shuts down the chip and reduces the supply current to less than 1μA.
The EN pin also accepts PWM signal for LED bright...
