OB3360 is a high integrated and high performance Light Emitting Diode (LED) driver optimized for LCD monitor backlight application. It integrates 8 channels of current source to drive LED arrays, and thus provides a cost effective and high reliability LCD backlight solution. OB3360 operates in current mode boost topology, and supports various dimming functions and comprehensive protections.
Features:
¡ô Minimal required external components
¡ô Current mode boost topology
¡ô ¡À3% matching accuracy between 8 LED strings control current
¡ô High precision reference and Selective-Frequency (160KHz/320KHz/640KHz/1.2MHz) control
¡ô External programmability of the key parameters
¡ô Flexible Dimming mode Control:
¡ó Internal burst, external burst (LPWM) dimming control
¡ó 0-2V DC voltage or external PWM direct dimming control without external circuits
¡ó Dimming range programmable (100%~0%)
¡ô Comprehensive protection coverage:
¡ó Output over voltage protection (OVP)
¡ó Under voltage lockout
¡ó Open LED protection and programmable short LED protection
¡ó Over temperature protection (OTP)
¡ô Available in QFN24/TSSOP24 packages, RoHS compliant
Applications:
¡ô Notebook PC
¡ô LCD monitor
¡ô LCD TV
