LT3483ES6#TRMPBF

LT®3483 is a micropower inverting DC/DC converter with integrated schottky and one resistor feedback. The small package size, high level of integration, and use of tiny surface mount components yield a solution size as small as 40mm2. The devices feature a quiescent current of only 40µA at no load, which further reduces to 0.1µA in shutdown. A current limited, fixed off-time control scheme conserves operating current, resulting in high efficiency over a broad range of load current. A precisely trimmed 10µA feedback current enables one resistor feedback and virtually eliminates feedback loading of the output. A precisely trimmed 10µA feedback current enables one resistor feedback and virtually eliminates feedback loading of the output. Application includes LCD bias, handheld computers, battery backup, digital cameras, OLED Bias.

• One resistor feedback (other resistor inside), uses small surface mount components
• Output short circuit protected
• VIN operating range from 2.5 to 16V (TA = 25°C, VIN = 3.6V)
• Typical switch off-time is 300ns (TA = 25°C, VIN = 3.6V)
• Maximum quiescent current in shutdown is 1µA (V active high SHDN = GND, TA = 25°C)
• Typical switch VCESAT is 200mV (ISW = 150mA to GND, TA = 25°C)
• Typical SHDN input high voltage is 1.5V (TA = 25°C, VIN = 3.6V)
• 6-lead plastic TSOT-23 package
• Operating temperature rating range from -40°C to 85°C
