Description
two LEDs for the sub-display in cellular phones. The device is capable
of operating in either 1x (LDO) mode or 1.5x charge pump mode. All
LED pin currents are regulated and tightly matched to achieve
uniformity of brightness across the LCD backlight. An external
resistor (R

operation (3.3 V). A constant high-frequency switching scheme
(1 MHz) provides low noise and allows the use of very small value
ceramic capacitors.
