TCR5AM065, LF Application Field and Working Principle

Introduction

TCR5AM065 is the first in a family of low-frequency, pulse-width-modulating (PWM) linear power supply regulators from Sipex. The device includes a precision-current source and a full-wave logarithmic-derivative (FLD) feedback loop for improved accuracy, high noise immunity and fast transient response. Its high peak output current and low supply current, combined with its wide range of output voltages, make the device suitable for a variety of applications, including cellular phones, PDAs and other portable equipment.

Field of Application

The TCR5AM065 is used in a wide range of applications, such as cellular phones, PDAs and other portable equipment. It is an ideal candidate for providing power to microprocessors, memory and other voltage-sensitive components. It can also be used in battery management systems, power amplifiers and audio applications. The device is capable of delivering up to 800mA of output current and can provide an output voltage as low as 0.8V and as high as 5.5V.

Working Principle

The working principle of the TCR5AM065 is based on a pulse-width-modulated (PWM) linear voltage regulator topology. The device uses a control loop consisting of three stages: a precision-current source, a full-wave logarithmic-derivative (FLD) feedback loop and a switching circuit. The current source is used to monitor the output voltage and provide a reference voltage to the FLD loop. The FLD loop uses the reference voltage to compare the output voltage to the desired voltage and adjusts the output voltage accordingly. The switching circuit is used to modulate the output voltage and provide a PWM output.

Conclusion

The TCR5AM065 from Sipex is a low-frequency, pulse-width-modulated (PWM) linear power supply regulator that can be used in a wide range of applications. It can deliver up to 800mA of current and provides an output voltage as low as 0.8V and as high as 5.5V. The device uses a control loop consisting of a precision-current source, a full-wave logarithmic-derivative (FLD) feedback loop and a switching circuit to modulate the output voltage and provide a PWM output.
