LT3489EMS8E#PBF

LINEAR TECHNOLOGY  LT3489EMS8E#PBF  直流-直流开关升压稳压器, 可调, 2.6V-16V输入, 2.6V-40V输出, 2.5A输出, MSOP-8

The is a fixed frequency step-up DC-to-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 profile inductors and low value ceramic capacitors. Loop compensation can be either internal or external, giving the user flexibility 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.
