LT1173CS8-5#PBF Description

Short technical summary and product information.

The LT1173CS8-5#PBF is a micropower DC-DC converter from Linear Technology, designed for versatile applications. It operates efficiently with supply voltages ranging from 2.0V to 30V, making it suitable for various power management needs.

This device consumes a minimal 110µA of supply current in standby mode, ideal for battery-powered and low-power applications. It functions effectively in step-up, step-down, or inverting configurations, requiring only three external components for operation. The LT1173CS8-5#PBF can deliver specific output currents depending on the input voltage and operating mode, such as 80mA at 5V from a 3V input in step-up mode or 200mA at 5V from a 12V input in step-down mode.

Key features include an internal 1A power switch and a user-adjustable current limit. An auxiliary gain block can be configured for additional functions like a low battery detector or an under-voltage lockout circuit. The device is available in space-saving 8-pin MiniDIP or SO8 packages, facilitating compact designs.

Applications for the LT1173CS8-5#PBF include flash memory Vpp generators, 3V to 5V and 5V to 12V converters, LCD bias generators, battery backup supplies, and portable instruments.
