LT1303 - Linear Technology

LT1303 Micropower High Efficiency DC/DC Converters with Low-Battery Detector Adjustable and Fixed 5V

The LT®1303/LT1303-5 are micropower step-up high efficiency DC/DC converters using Burst ModeTM operation. They are ideal for use in small, low-voltage batteryoperated systems. The LT1303-5 accepts an input voltage between 1.8V and 5V and converts it to a regulated 5V. The LT1303 is an adjustable version that can supply an output voltage up to 25V. Quiescent.

They are ideal for use in small, low-voltage batteryoperated systems. The LT1303-5 accepts an input voltage between 1.8V and 5V and converts it to a regulated 5V. The LT1303 is an adjustable version that can supply an output voltage up to 25V. Quiescent current is only 120µA from the battery and the shutdown pin further reduces current to 10µA. The low-battery detector provides an opencollector output that goes low when the input voltage drops below a preset l.
