This document introduces the features and characteristics of the LT8410/-1 high efficiency boost converter. The converter only requires 8.5μA of quiescent current in standby mode, and integrates high value (12.4M/0.4M) output feedback resistors, significantly reducing input current when the output is in regulation with no load. It also has built-in soft-start, overvoltage protection and a wide input range.
The LT8410/-1 is a high-efficiency boost converter designed for industrial remote monitoring systems and battery-powered applications. It features 8.5µA quiescent current in standby mode and integrated high-value feedback resistors to reduce input current when output is regulated with no load. The device includes an integrated 40V switch and Schottky diode, output disconnect with current limit, soft-start, overvoltage protection, and a wide input range, all in a compact 8-pin 2mm × 2mm DFN package.
It is ideal for applications requiring low power consumption and high efficiency, especially when operating from high-impedance sources like coin cell batteries. The converter can regulate a 16V output from a 2.5V to 16V input, with output ripple less than 10mV despite a small 0.1µF output capacitor. The device also integrates an output disconnect PMOS to block the output load during shutdown, with current limiting to protect against output shorts.
