LED Drivers
The ISL97692, ISL97693, ISL97694A are Intersil’s highly
integrated 4-and 6-channel LED drivers for display
backlighting. These parts maximize battery life by featuring
only 1mA quiescent current, and by operating down to 2.4V
input voltage, with no need for higher voltage supplies. Features The ISL97692 has four channels and provides 8-bit PWM
dimming with adjustable dimming frequency up to 30kHz. The
ISL97693 has six channels with Direct PWM dimming control.
The ISL97694A has 6 channels and provides 8-, 10-, or 12-bit
PWM dimming with adjustable dimming frequency up to
30kHz, 7.5kHz, or 1.875kHz, respectively, controlled with I2C
or PWM input. 90% efficient at 6P5S, 3.7V and 20mA (ISL97693, ISL97694A) The ISL97692 and ISL97694A feature phase shifting that may
be enabled optionally, providing an optimized phase delay
between channels. In the ISL97692 and ISL97694A, phase
shifting can multiply the effective dimming frequency by four
and six allowing above audio-band PWM dimming with 10-bit
dimming resolution.
The ISL97692, ISL97693, ISL97694A employ adaptive boost
architecture, which keeps the headroom voltage as low as …
