***th Star Micro
The CAT4106 is an integrated multi-channel LED driver and high power dc-dc converter suitable for powering backlighting applications up to a total of 6 watts. Up to four matched LED strings can be accurately programmed with uniform drive current set by a single external resistor. Each output channel is suitable for LED string voltages of up to 36 V. The driver automatically adjusts the output voltage to drive the highest forward voltage string with the minimum headroom voltage maximizing the efficiency. High resolution dimming control is achieved by the EN/PWM logic pin which supports multiple frequencies. This ensures precise PWM dimming control while the device remains fully biased. In addition when held at logic low the device to enter a full shutdown zero current mode. External programming resistors set the minimum and maximum voltage limits for the acceptable window of operation for LED strings. Any channel which fails to regulate within the window (Open or Short LED) is detected and flagged on the FAULT logic output (active low open-drain). The device is available in a 16-lead TQFN 4 mm x 4 mm and TSSOP with exposed pad packages.
***AS INSTUMENTS
The LM3639A is a single-chip white LED Camera Flash Driver + LCD Display Backlight Driver. The low-voltage, high-current flash LED driver is a synchronous boost which provides the power for a single flash LED at up to 1.5A or dual LEDs at up to 750 mA each. The high-voltage backlight driver is a dual-output asynchronous boost which powers dual LED strings at up to 40V and 30 mA per string. An adaptive regulation method in both boost converters regulates the headroom voltage across the respective source/sink to ensure the LED current remains in regulation while maximizing efficiency. The LM3639A's flash driver is a 2MHz or 4MHz fixed-frequency synchronous boost converter plus 1.5A constant current driver for a high-current white LED. The high-side current source allows for grounded cathode LED operation providing Flash current up to 1.5A. An adaptive regulation method ensures the current source remains in regulation and maximizes efficiency.
***AS INSTRUMEN
The device is controlled by an I2C-compatible interface. Features for the flash LED driver include a hardware flash enable (STROBE) allowing a logic input to trigger the flash pulse, and a TX input for synchronization to RF power amplifier events or other high current conditions. Features for the LCD backlight driver include a PWM input for content adjustable backlight control, 128 exponential or linear brightness levels, programmable over-voltage protection, and selectable switching frequency (500 kHz or 1 MHz).
***AS USD
The device is available in a tiny 1.790 mm x 2.165 mm x 0.6 mm 20-bump, 0.4 mm pitch DSBGA package and operates over the −40°C to +85°C temperature range.
