LT1170IT#PBF Application Field and Working Principle
LT1170IT#PBF is a monolithic, high performance DC to DC switching regulator. It offers an innovative hybrid technology combining the advantages of a current-mode PWM controller, a high speed DMOS power switch, and a unique current sense amplifier. As a result, it offers low voltage/high current mode control with exceptional transient response, resulting in current-mode performance at voltage-mode cost.
Its primary application field includes automotive, telecommunications, industrial, computer, and consumer electronics. LT1170IT#PBF is used in low voltage/high current supplies and the voltage can be adjusted over the range of 0.8V to 16V.
Working Principle
LT1170IT#PBF works as a voltage regulator. The voltage input is filtered and regulated with the help of an internal Stepdown or Step-up converter. By controlling the output of the converter, the output voltage required is obtained. The regulator also has an adjustable current limit protection, making it suitable for applications where high output capacitance is present.
The working of the LT1170IT#PBF involves the use of an internal PWM controller, a DMOS power switch, and a current sense amplifier. The unused energy from the switching cycle is stored in a small integrated capacitor, which is then used in the ensuing cycle. This helps in achieving low voltage and high current mode control with superior transient response.
Summary
In conclusion, LT1170IT#PBF is a monolithic high performance DC to DC switching regulator, and its primary application field covers automotive, telecommunications, industrial, computer, and consumer electronics applications. LT1170IT#PBF offers low voltage/high current mode control with superior transient response, making it suitable for applications where high output capacitance is present. Additionally, it has an adjustable current limit protection, allowing it to be used in more custom power supply solutions and designs.
