MAX1582Y - High-Efficiency / 26V Step-Up Converter

Download the MAX1582Y datasheet PDF. This datasheet also covers the MAX1582 variant, as both devices belong to the same high-efficiency / 26v step-up converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX1582/MAX1582Y drive up to six white LEDs in series with a constant current to provide display backlighting for two (main and sub-) displays in cell phones and other handheld devices.

This configuration eliminates the need for ballast resistors and expensive factory calibration.

Key Features

  • Accurate Current Regulation for Uniform Illumination.
  • Lights Up Two LED Sections for Main and Subdisplays.
  • Up to 84% Efficiency.
  • Internal High-Power, 30V MOSFET.
  • Low 15mVP-P Input Ripple.
  • Flexible Dimming Control Analog DAC Controlled Direct-Digital PWM (No RC Required) from 200Hz to 200kHz.
  • Overvoltage Protection to Eliminate Zener Diode.
  • Constant 1MHz PWM Operation.
  • Low-Profile Inductor and Capacitors.
  • S.

19-2783; Rev 2; 8/05 EVAALVUAAILTAIOBNLEKIT High-Efficiency Step-Up Converters for White LED Main and Subdisplay Backlighting MAX1582/MAX1582Y General Description The MAX1582/MAX1582Y drive up to six white LEDs in series with a constant current to provide display backlighting for two (main and sub-) displays in cell phones and other handheld devices. This configuration eliminates the need for ballast resistors and expensive factory calibration. The proprietary dual-output, step-up pulse-width modulation (PWM) converter includes a low RDSON n-channel MOSFET switch for high efficiency and maximum battery life.
