LM3632EVM
概述
The LM3632EVM aids in evaluation of the LM3632 Single-Chip Backlight + Bias Power + 1.5-A Flash LED Driver.
The LM3632 contains 3 major blocks:
- A high efficiency backlight driver capable of driving 2 LED strings of up to 8 LEDs per string.
- A set of positive and negative bias supplies of programmable reference voltage for powering LCD drivers.
- A 1.5-A constant current LED driver powered by a synchronous boost converter for camera flash applications.
The LM3632EVM and supporting software provides all of the control mechanisms to demonstrate the functionality of all 3 blocks of the LM3632. Control includes I2C interface as well as external control via access to all LM3632 pins.
特性
- Dual, 11-bit (2048 levels), 25-mA max backlight LED strings
- User programmable, 50-mA max VPOS & VNEG bias power supplies
- Single 1.5-A flash LED driver with 16 levels of current level programmability
- I2C Control for all functions
- External Controls (General Enable, PWM for backlight, independent enable pins for bias power, Strobe and Tx pins for flash driver)
