DESCRIPTIO
Flexible Power Supply Tracking and Sequencing Adjustable Ramp Rates, Offsets and Time Delays Controls Three Supplies with Series MOSFETs Integrated Remote Sense Switching FAULT Input/Output STATUS Output/Power Good Input Available in 20-Lead Narrow SSOP and 20-Lead QFN (4mm × 5mm) Packages
The LTC2926 provides a simple solution for tracking and sequencing up to three power supply rails. An N-channel MOSFET and a few resistors per channel configure the load voltages to ramp up and down together, with voltage offsets, with time delays or with different ramp rates. Automatic remote sense switching compensates for voltage drops across the MOSFETs.
