This article introduces the features of the LT8410/-1 DC/DC boost converter, including ultra-low quiescent current, integrated high value feedback resistors, and output disconnect.
The LT8410/-1 is a DC/DC boost converter designed for industrial remote monitoring and keep-alive circuits. It features ultralow quiescent current (8.5µA) and integrated high-value feedback resistors to minimize battery drain during idle operation. It supports a 2.5V to 16V input range and up to 40V output, with low output ripple and output disconnect for shutdown. The device is available in a compact 2mm × 2mm DFN package and is stable with small ceramic capacitors.
The LT8410/-1 includes a programmable shutdown voltage via external resistors, soft-start capability via VREF, and internal Schottky diode and switch current limits (25mA for LT8410, 8mA for LT8410-1) for compatibility with high-impedance sources like coin cell batteries.
