Product details

Description

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.

Features

a temperature derating function to avoid overdriving the white LEDs during high ambient temperatures, enabling higher drive current below +42°C. The MAX1578/MAX1579 are available in space-saving 24-lead 4mm x 4mm thin QFN packages. 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.
