LT3467AES6#TRPBF

LT3467A switching regulator combine a 42V, 1.1A switch with a soft-start function. Pin compatible with the LT1930, its low VCESAT bipolar switch enables the device to deliver high current outputs in a small footprint. High inrush current at start-up is eliminated using the programmable soft-start function. A single external capacitor sets the current ramp rate. A constant frequency current mode PWM architecture results in low, predictable output noise that is easy to filter. Typical applications are digital cameras, white LED power supplies, cellular phones, medical diagnostic equipment, local 5V or 12V supplies, TFT-LCD bias supplies, xDSL power supplies.

• Switches at 2.1MHz, allowing the use of even smaller components
• Low VCESAT switch is 330mV at 1.1A
• Dedicated soft-start pin
• Uses small surface mount components
• Pin-for-pin compatible with the LT1930 and LT1613
• Minimum operating voltage is 2.2 to 16V
• FB pin bias current is 50nA at TA = 25°C. VIN = 3V, VSHDN = VIN
• 6-lead plastic TSOT-23 package
• Temperature range from –40°C to 85°C
