IS32LT3175N/P Single-Channel Linear LED Drivers

ISSI IS32LT3175N/P Single-Channel Linear LED Drivers come with fade in/out and PWM dimming. The regulators serve as a stand-alone LED driver-configurable from 20mA to 150mA with external resistors, no microcontroller is necessary. A logic level “courtesy light” signal from the PWM pin can be interfaced to precisely drive the LED channel. The IS32LT3175P obtains a positive polarity PWM signal. In addition, the IS32LT3175N obtains a negative polarity PWM signal. The regulator integrates a 63-step fade-in and fades out the algorithm (Gamma correction). This causes the output LED current to increasingly rise up to the full source value after the EN pin is pulsed.

LM3645 LED Driver IC

Texas Instruments LM3645 LED Driver IC is a synchronous boost quad LED flash driver with 2A high-side current source. This LED driver provides a high level of adjustability within a small solution size. The LM3645 driver incorporates a 2MHz or 4MHz constant frequency-synchronous current-mode PWM boost converter. This LED driver features quad-high-side current sources to regulate the LED current over the 2.3V to 5.5V input voltage range. Features include dual hardware flash pins and hardware torch or Tx interrupt pin (STR1, STR2, and TORCH/TX), and dual NTC thermistor monitors. The LM3645 IC is ideal for camera phones with white LED flash, digital still cameras, barcode scanners, and handheld data terminals.
