Description

General part information

LT1946 Series

The LT1946 is a fixed frequency step-up DC/DC converter containing an internal 1.5A, 36V switch. Capable of generating 8V at 430mA from a 3.3V input, the LT1946 is ideal for large TFT-LCD panel power supplies. The LT1946 switches at 1.2MHz, 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.The 8-lead MSOP package and high switching frequency ensure a low profile overall solution less than 1.2mm high.Switching FrequencyLT19461.2MHzLT1946A2.7MHzApplicationsTFT-LCD Bias SuppliesGPS ReceiversDSL ModemsLocal Power Supplies
