LT1930ES5#TRPBF

LT1930 is the industry’s highest power SOT-23 switching regulator. This includes an internal 1A, 36V switch allowing high current outputs to be generated in a small footprint. The LT1930 switches at 1.2MHz, allowing the use of tiny, low cost and low height capacitors and inductors. Complete regulator solutions approaching one tenth of a square inch in area are achievable with these devices. Multiple output power supplies can now use a separate regulator for each output voltage, replacing cumbersome quasi-regulated approaches using a single regulator and custom transformers. A constant frequency internally compensated current mode PWM architecture results in low, predictable output noise that is easy to filter. Typical applications are TFT-LCD bias supply, digital cameras, cordless phones, battery backup, medical diagnostic equipment, local 5V or 12V supply, external modems, PC cards, xDSL power supply.
