Product Description

DESCRIPTION
The LM3630A is a current mode boost converter which supplies the power and controls the current in up to two strings of 10 LEDs per string. Programming is done over an I2C-compatible interface. The maximum LED current is adjustable from 5 mA to 28.5 mA. At any given maximum LED current the LED brightness is further adjusted with 256 exponential or linear dimming steps. Additionally, pulsed width modulation ("PWM") brightness control can be enabled allowing for LED current adjustment by a logic level PWM signal.
FEATURES
• Drives up to 2 strings of 10 series LEDs
• Up to 87% efficient
• 8-bit I2C-Compatible Programmable Exponential or Linear Brightness Control
• PWM Brightness Control for CABC Operation
• Independent Current Control per String
• True Shutdown Isolation for LEDs
• Internal Soft-Start Limits Inrush Current
• Wide 2.3V to 5.5V Input Voltage Range
• Adaptive Headroom
• Programmable 16V/24V/32V/40V Over-Voltage Protection
• Selectable Boost Frequency of 500 kHz or 1MHz with optionally additional offset
• Low Profile 12-Bump DSBGA Package
• Solution Size 32mm²
APPLICATIONS
• Smart-Phone LCD Backlighting
• LCD + Keypad Lighting
