ISL97691 Overview
It drives four 40mA channels of LEDs up to 26V from an input supply 2.4V to 5.5V. The ISL97691 will also drive 60mA channels up to 21V at 30% duty for high peak current 3D modes. The ISL97691 provides 4 channels of current with 2 independent analog dimming controls and 2 independent PWM dimming controls.
ISL97691 Key Features
- 2.4V minimum input voltage, no need for higher voltage supplies
- 2 groups of independent analog and pwm current controls
- 1-wire interfaces for 6-bit analog dimming
- PWM inputs for PWM dimming
- 0.005% minimum PWM dimming duty cycle at 100Hz
- Low 0.8mA quiescent current
- ±2.5% current matching
- Adjustable switching frequency from 400kHz to 1.5MHz
- Fault protection
- OVP, OTP, channel open/short circuit protections
ISL97691 Applications
- 2.4V minimum input voltage, no need for higher voltage supplies
