Overview

Preliminary RT9272 High Performance, Constant Current LED Driver for Dual Panel Mobile Phone General Description The RT9272 is a high efficiency step-up DC-DC converter specifically designed for dual panel mobile phone applications.
According to SP status, RT9272 can either regulates output current flowing through series-connected LEDs for main panel or for sub panel 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 brightne...
