Introduction

ICL7663SAIBAZA is a voltage regulator of the ‘Linear’ type, which is one of the most reliable and widely used type in the “Power Management IC” (PMIC) family. This voltage regulator has been specially designed for applications, which require an accurate output voltage with low power consumption. It is particularly suited to applications in the automotive, high end consumer and industrial instruments segments, and the most attractive benefit of using this voltage regulator is its minimum shutdown current consumption of less than 1uA, even when operating with a 3.6V operating voltage.

The Features and Benefits

The ICL7663SAIBAZA voltage regulator features a wide input voltage range of 4.5V to 28V and an output voltage range of 2.5V to 28V. This enables it to meet the wide range of application requirements in automotive and high end consumer as well as industrial instrumentation fields. The switching frequency range of this PMIC is adjustable and can extend up to 2MHz, making it suitable for high frequency applications too.This PMIC has a very low quiescent current consumption and its maximum output current is guaranteed at 1Amps. It is designed to have a very low dropout voltage of 0.2V at 1A load current and 0.5V at 0.5A load current. This feature along with its low quiescent current consumption makes it suitable for applications where power consumption is a key consideration.The ICL7663SAIBAZA adopts a unique 140-pin thin MLF package which offers compactness as well as low profile and ensures easy mounting onto a PCB. This feature makes it suitable for slim profile applications.

The Applications

The ICL7663SAIBAZA has a wide range of applications in the automotive,high end consumer and industrial instruments segments. In automotive, it can be used for charging the battery and controlling the various output voltages for the various components of the system. It can also be used for DC to DC modules for the electronic power steering, climate control systems and engine controls. Additionally, it can also be used for alternator voltage control, motor speed controls and fuel gauge implementations.In the high end consumer arena, applications such as digital TV and DVD players, mobile phones and notebooks, as well as LCD monitors and projectors can benefit from the low quiescent current and low dropout voltage characteristics of the ICL7663SAIBAZA. Furthermore, it can also potentially be used in gaming consoles, digital cameras and other electronic devices that need to run on a reliable power supply.In the industrial arena, the ICL7663SAIBAZA voltage regulator can be used for supplying the various voltages for industrial instruments such as control systems for motors and industrial HVACs. Similarly, it can also be used in sensing, control and power management systems as well as in energy management systems to stimulate and monitor the energy flow.

The Working Principle

The working principle of the ICL7663SAIBAZA is based on linear technology, which is also the basis of most of the power management ICs available on the market. Linear voltage regulation uses as a feedback loop which senses the output voltage of the regulator with a precision reference voltage and compares it with a desired output voltage. Depending upon the comparison, it adjusts the output voltage in order to maintain it at the desired voltage level.To illustrate the working principle of the ICL7663SAIBAZA, we can consider the example of a digital TV, where the current being drawn by the TV is constantly changing and the voltage needs to be regulated in order to maintain the quality of the picture. In this case, an internal sense resistor senses the voltage across the output of the TV, which is then compared to a precision reference voltage. If the voltage is higher than the referenced voltage, the output voltage of the TV is reduced by controlling the power supply MOSFET gate pulse width. Similarly, if the voltage is lower than the referenced voltage, the output voltage of the TV is increased by the same control mechanism.

Conclusion

The use of the ICL7663SAIBAZA as a voltage regulator has been proven to be cost effective and efficient in applications which require an accurate output voltage with low power consumption. It is particularly suited to applications in the automotive, high end consumer and industrial instruments segments due to its low dropout voltage, wide input voltage range and low quiescent current consumption. Its 140-pin thin MLF package design coupled with its high switching frequency offers flexibility and practicality for a wide range of industrial,consumer and automotive applications.
