TWL6030B1A4CMRR Application Field and Working Principle

The TWL6030B1A4CMRR is an analog and mixed signal power management integrated circuit (PMIC). This device is designed to provide low power, high efficiency and highly reliable power management within a wide range of applications, from consumer to medical and industrial.

The device integrates a range of linear, switching and regulator functions for a variety of power management requirements. It includes a step down converter (SD), pulse-width modulated (PWM) DC-DC converters, low-voltage (LDO) and ultra-low voltage (ULV) linear regulators, pulse-width modulated (PWM) LED flash drivers and LED drivers, low-dropout (LDO) regulators, temperature sensor, voltage supervisor, real time clock (RTC) and system peripherals. It is capable of providing up to 8A just from one of its two PWM buck converters, and up to 3A from its two LDOs.

The TWL6030B1A4CMRR is suitable for a wide range of applications including mobile phones, tablets, notebooks, LCD and plasma displays, digital cameras, portable media players, automotive infotainment and secure access control, tablets and gaming systems, digital and smart lighting, medical devices, and industrial and networking systems, among others.

Working Principle

The TWL6030B1A4CMRR is designed with an integrated buck, boost and boost-buck converter architecture. The device integrates two buck converters and one boost converter, which are powered by an external supply voltage. The buck converters convert the input voltage to a lower voltage and current. The boost converter is designed to step up the incoming voltage to a higher voltage and current. The TWL6030B1A4CMRR can also operate in boost-buck mode, which is the combined operation of both the buck and boost converters, allowing the device to support multiple output voltages.

The device includes two manually adjustable LDOs and two ultra low voltage (ULV) linear regulators, as well one white LED driver and two adjustable pulse-width modulated (PWM) LED drivers. All LDOs and linear regulators can be configured to accept inputs from DC-DC converters and provide output voltage up to 1.8V.

The device also includes a temperature sensor, voltage supervisor, real time clock (RTC) and system peripherals. The built-in voltage supervisor provides the user with an independent power-on reset circuit. The device provides a low power failure indication to report environment condition or power system event. The device also contains an embedded true random number generator (TRNG) for security applications.

The TWL6030B1A4CMRR is designed to operate in extreme temperature conditions, with an operating temperature range from -40 to +125 degrees Celsius. The device is also designed to meet the needs of both general purpose operation and industrial operation. The device is packaged in a compact QFN package and is available in an RoHS-compliant solution.

Conclusion

The TWL6030B1A4CMRR is an integrated analog and mixed signal PMIC, designed for a broad range of applications from consumer and medical to industrial. The device is designed to provide low-power, high efficiency, and highly reliable power management, with two buck converters, one boost converter and two LDOs, as well as a wide range of other features such as temperature sensor, real time clock, voltage supervisor and system peripherals. The device is suitable for a variety of applications and is packaged in a compact QFN package.
