Sep 19, 2017 High Efficiency Display Power and LED Driver for Smart Phones
The ISL98611A is a high efficiency display power supply and
LED driver for small size displays such as smart phones. It
integrates a boost regulator, LDO, and inverting charge pump
that are used to generate two output rails for the display
power: +5V (default) and -5V (default). It also integrates a
boost regulator and 3-channel current sinks for the LED
backlight driver. The В±5V output voltages can be adjusted from
В±4.5V up to В±6V. Features ISL98611A extends the battery life of mobile devices by
delivering greater than 87% efficiency for the display power
function. For a backlight driver the ISL98611A uses
nonsynchronous rectification, and by using a 3-channel
topology the ISL98611A provides more than 90% efficiency.
The ISL98611A integrates all compensation and feedback
components, which minimizes BOM count and reduces the
solution PCB size. В±2.2% current matching down to 1mA This product drives backlight LEDs with excellent current
matching even at very low LED current (В±2.2% down to 1mA),
improving the brightness uniformity of LCD displays. It includes
analog, PWM and hybrid dimming to maximize LED efficiency
while eliminating color shift issues. 2.5V to 5V input voltage range The ISL98611A is offered in a 2.33x2.61mm2 WLCSP …
