LINEAR TECHNOLOGY - 1 LTC1553 5 handbook

Update: 28 September, 2023

The LTC1553 is a high power, high efficiency switching regulator controller optimized for 5V or 12V input to 1.8V-3.5V output applications. It features a digitally programmable output voltage, a precision internal reference, and an internal feedback system that provides output accuracy of ±1.5% at room temperature and typically ±2% over-temperature, load current, and line voltage shifts. The LTC1553 uses a synchronous switching architecture with two external N-channel output devices, providing high efficiency and eliminating the need for a high power, high-cost P-channel device. Additionally, it senses the output current across the on-resistance of the upper N-channel FET, providing an adjustable current limit without an external low-value sense resistor.
