BQ24640RVAR

Modern society is surrounded by sophisticated technologies that require precision measurements, power conservation, and safety features. Power Management IC (PMIC) is a type of semiconductor device that manages the electrical power within a system. Specialized PMIC, such as the BQ24640RVAR, is designed to streamline the power management of electric systems, providing the most efficient power management solutions.The BQ24640RVAR is a multi-rail switchable synchronous pulse width modulation (PWM) buck converter. This PMIC is capable of providing up to 10A output current for its multiple output rails. It can work in an input voltage range of 5.5V to 16V and also has a low quiescent current of 5 microamps, thus making it ideal for battery operated applications. This device is highly optimized for Intel microcontrollers, such as the Atom processors and Intel SoC platforms, providing better power savings due to reduced ripple and output noise, which are essential for systems\' energy efficiency.The main application field of the BQ24640RVAR is high-performance computing and data centers. It can be used in servers, storage and other high-performance system-on-chip (SoC) devices. It is also widely used in automotive, industrial, medical and other industrial grade devices.The working principle of the BQ24640RVAR is simple. It consists of four independent channels that generate an adjustable voltage output. The output voltage of each channel can be set through external voltage divider resistors. The output current of each channel can be set using an external current sense resistor. This PMIC features an independent enable pin and ERR output pin, which allows the user to monitor the power supply status. The BQ24640RVAR also comes with an advanced low-noise pulse width modulation (PWM) scheme, called the Active Ripple Reduction (ARR). This scheme reduces the ripple by actively controlling the PWM duty cycle based on the load current, thus minimizing the output noise. The protection features of the BQ24640RVAR include over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), and over-temperature protection (OTP). The device also features an internal soft start mechanism that protects the system from inrush current.The BQ24640RVAR is a highly efficient PMIC with a wide input voltage range, low quiescent current, and advanced power management and protection features. This device is ideal for applications that require a reliable, flexible, and energy-efficient power supply solution.
