ISL97698IIZ-T規(guī)格書詳情

The ISL97698 is a highly integrated 2-channel LED driver for

white LED (WLED) backlit TFT-LCD panels. The device is

comprised of a synchronous boost converter and two low-side

current sinks that are capable of driving an output voltage up

to 23.5V and 25mA LED current, per string. The IC operates

from an input supply of 2.5V to 5.5V.

The driver features Dynamic Headroom Control that monitors

the highest LED forward voltage string to determine the

requested boost output voltage. With a controlled low 70mV

headroom voltage and low 0.35mA IC supply current, the

device provides very high efficiency.

The ISL97698 offers 8-bit linear or 11-bit logarithmic

controlled analog output current, with dimming control from a

PWM, SWIRE, or I2C interface. Internally, the PWM duty cycle,

SWIRE, and I2C digital inputs are converted to a DC LED

current. This analog dimming scheme provides high efficiency

and eliminates audible noise and PWM dimming related EMI

concerns. The ISL97698 also features Content Adaptive

Backlight Control (CABC), which uses the product of the PWM

and SWIRE, or PWM and I2C, or SWIRE and I2C inputs to

determine the LED string current. The I2C interface is also

used for configuration settings and fault detection. The

ISL97698 incorporates various protections including: open

circuit, short circuit, and thermal shutdown.

The device is offered in a 1.39mmx 1.69mm, 3x4 array

WLCSP package. It is specified for operation over the -40°C to

+85°C ambient temperature range
