The LTC1550LCS8-4.1 is a charge pump DC-DC converter from Analog Devices that delivers a fixed -4.1V output from a 4.5V to 5.5V input. It supports up to 20mA of output current and operates at 900kHz, allowing for small external capacitors. The 8-SOIC package is well-suited for applications requiring a negative rail, including precision DACs, telecom line cards, and medical devices.
- Fixed -4.1V Output: Provides a precise negative rail without external adjustment components.
- High Switching Frequency: 900kHz reduces capacitor size and output ripple for clean power.
- Wide Input Tolerance: Accepts 4.5V to 5.5V, covering standard 5V supplies.
- Compact Package: 8-SOIC footprint saves board space in dense designs.
Negative Rail for Precision DACs
Provide a -4.1V supply for digital-to-analog converters (DACs) in industrial control systems. The 900kHz switching frequency ensures low noise, critical for accurate analog output.
Portable Test Equipment
Generate a negative bias for LCD displays in handheld oscilloscopes or signal generators. The fixed output simplifies design and reduces component count.
Telecom Line Cards
Supply a negative voltage for line driver circuits in networking equipment. The 8-SOIC package fits dense PCB layouts, and the 20mA output is adequate for interface ICs.
Medical Monitoring Devices
