ISL97692IRTZ Détails du produit

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.
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.
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
possible to maximize battery life while allowing ultra low
dimming duty cycle as low as 0.005% at 100Hz dimming
frequency in Direct PWM mode.
The ISL97692, ISL97693, ISL97694A incorporate extensive
protection functions including string open and short circuit
detections, OVP, and OTP.
The ISL97692, ISL97693 are offered in the 16 Ld 3x3mm TQFN
package, and a 16 bump 1.7x1.7mm WLCSP for the ISL97692.
The ISL97694A is offered in the 20 Ld 3x4mm TQFN package. All
parts operate in ambient temperature range of -40°C to +85°C.

Features
• 2.4V minimum input voltage, supports single cell applications
• 4 channels, up to 40mA each (ISL97692) or 6 channels, up to
30mA each (ISL97693, ISL97694A)
• 90% efficient at 6P5S, 3.7V and 20mA (ISL97693, ISL97694A)
• Low 0.8mA quiescent current
• PWM dimming control with internally generated clock
- 8-bit resolution with adjustable dimming frequency up to
30kHz (ISL97692, ISL97694A)
- 12-bit resolution with adjustable dimming frequency up to
1.875kHz (ISL97694A)
- Optional automatic channel phase shift (ISL97692,
ISL97694A)
- Linear dimming from 0.025%~100% up to 5kHz or
0.4%~100% up to 30kHz (ISL97692, ISL97694A)
• Direct PWM dimming with 0.005% minimum duty cycle at
100Hz
• ±2.5% output current matching
• Adjustable switching frequency from 400kHz to 1.5MHz

Applications
• Tablet, Notebook PC and Smart Phone Displays LED
Backlighting
