AAT1402 - Serial LED Driver

Description

The AAT1402 is a step-up single channel LED driver with an input voltage range of 2.7V to 5.5V.

Features

  • and high efficiency are suitable for LED backlight solutions for single cell Li-ion based equipment. A precision high voltage current sink maintains the maximum LED current set by an external resistor from 10 to 31mA to drive 8 series connected LEDs. The high switching frequency supports ultra-small, low-cost filtering components. Two dimming controls are available: 32 dimming steps using S2Cwire and filtered PWM control. The frequency range of the PWM dimming extends up to 100kHz, eliminating a.

DATA SHEET AAT1402 Serial LED Driver with Filtered PWM and 32-Step S2C Dimming Control General Description The AAT1402 is a step-up single channel LED driver with an input voltage range of 2.7V to 5.5V. The wide input voltage, small solution size, advanced dimming features and high efficiency are suitable for LED backlight solutions for single cell Li-ion based equipment. A precision high voltage current sink maintains the maximum LED current set by an external resistor from 10 to 31mA to drive 8 series connected LEDs. The high switching frequency supports ultra-small, low-cost filtering components. Two dimming controls are available: 32 dimming steps using S2Cwire and filtered PWM control.
