Introduction to LTC4235IUFD-2#TRPBF

The LTC4235IUFD-2#TRPBF from Linear Technology Corporation is a Hot Swap Controller that gives continuous power delivery to an uncontrollable powered load. It provides fast and safe dynamic load control by controlling an n-channel MOSFET in a buck topology. The onboard adaptive programmability, glitch-free power sequencing, safe power-up and power-down sequencing, and hot swap detection circuitry make this controller ideal for use in critical power applications.

Application field of LTC4235IUFD-2#TRPBF

The LTC4235IUFD-2#TRPBF thus is a great choice for many power applications such as pluggable loading, redundant power modules, x86 servers and blade servers, power management applications, memory modules, modems and other communication equipment, and multi-function I/O boards.This controller can also be used in hot swap applications, providing continuous uninterrupted power to a cable or bus during operation and/or removal or insertion of a powered device. It allows hot swapping of a powered load from a mains power source without any interruption of the load.The LTC4235IUFD-2#TRPBF also finds application in Automotive and Motor Control applications, where it is used to provide protection against over-power and over-voltage.

Working principle

The LTC4235IUFD-2#TRPBF has an integrated drive capability, allowing it to control an n-channel MOSFET in a buck topology. In operation, the controller monitors the voltage at both the V1 and V2 pins, and then exaggerates the difference between the two. The resulting difference is then amplified and sent to the N-channel MOSFET gate as the gate drive voltage.The controller also integrates a thermal shutdown protection feature, and can protect against an over-power or over-voltage condition. When either of these conditions is detected, the controller will shut down the output and turn off the connected device.The LTC4235IUFD-2#TRPBF also has a hysteretic current mode control (HCC) feature, which helps to keep the power supply current and voltage within specified limits. This feature keeps the delivered power constant and protects against slow load variations.

Conclusion

To summarize, the LTC4235IUFD-2#TRPBF is a Hot Swap Controller from Linear Technology Corporation. It provides continuous uninterrupted power to the load during insertion or removal, and also provides protection against over-power and over-voltage. It is suitable for many power applications such as pluggable loading, redundant power modules, x86 servers and blade servers, power management applications, etc. The hysteretic current mode control feature of the LTC4235IUFD-2#TRPBF helps to keep the delivered power constant and the device protected against slow load variations.
