功能描述

The LT3489 is a ?xed frequency step-up DC/DC converter containing an internal 2.5A, 40V switch. The LT3489 is ideal for large TFT-LCD panel power supplies. The LT3489 switches at 2MHz, allowing the use of tiny, low pro?le inductors and low value ceramic capacitors. Loop compensation can be either internal or external, giving the user ?exibility in setting loop compensation and allowing optimized transient response with low ESR ceramic output capacitors. Soft-start is controlled with an external capacitor, which determines the input current ramp rate during start-up.

The 8-lead MS8E package and high switching frequency ensure a low pro?le overall solution less than 1.1mm high.
