The MAX1578/MAX1579 provide four regulated outputs to meet all the voltage requirements for small activematrix TFT-LCD displays in handheld devices where minimum external components and high efficiency are required. Each device consists of three advanced charge pumps for LCD bias power and a step-up converter for driving up to 8 series white LEDs for backlighting.
The input voltage range is from 2.7V to 5.5V.
Features
♦ Four Regulators in One Package
♦ Bias Power Using Charge Pumps +5V at 25mA for Source Driver +15V at 100µA for VON -10V at 100µA for VOFF No External Diodes Required Output Sequencing POS, NEG, and MAIN Are Autodischarged During Shutdown
♦ LED Backlight Power Using Boost Converter Series LED Connection for Uniform Illumination Supports Up to 8 LEDs at 25mA (max) 900mW (max) Power PWM or Analog Dimming Control Overvoltage Protection Low Input/Output Ripple Soft-Start with Zero Inrush Current Fast 1MHz PWM Operation for Small Component Size Temperature Derating Function (MAX1579)
♦ High Efficiency Bias: 83% (5.0V at 25mA, 15V/-10V at 100µA) LED: 84% (6 LEDs at 20mA)
♦ Uses Only Ceramic Capacitors and Only One Inductor
