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.
Note: The manufacturer provides a single datasheet file (MAX1582_MaximIntegratedProducts.pdf) that lists specifications for multiple related part numbers.

d 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.
