ISL6522CBZA-TR5190

The ISL6522CBZ-TR5190 switching voltage regulator module is an integrated circuit from Intersil that combines four charge pumps, a high-current LDO, two ultra-low-dropout linear regulators, two low-side switches, and high-side switches all in a very small form factor. This power management device is designed for applications where space is a major concern, such as smartphones and tablets. It is used to provide voltage regulation, circuit protection, power up/down sequencing, soft start, and system monitoring in a very efficient manner.

The ISL6522CBZ-TR5190 is a highly integrated power supply module that is used as a DC-DC switching controller. It has four regulated charge pump output channels with up to 2A of current per channel and adjustable output voltage. The adjustable output voltage allows the user to optimize their design for the specific application requirements. The device also incorporates two ultra-low-dropout linear regulators (ULDLRs), two low-side switches, and one high-side switching channel.

The charge pumps in the ISL6522CBZ-TR5190 use an oscillator to drive the switching frequency which can be adjusted from 10kHz to 1MHz. The charge pump operation is regulated by three control parameters: the transfer ratio, the peak current limit, and the duty cycle. The transfer ratio is the ratio between the output voltage and the input voltage and is set by the user. The duty cycle is set by the user and is used to control the amount of charge pumped during each cycle. The peak current limit is the maximum amount of current allowed for each of the four charge pumps and can be set via an external resistor.

The ISL6522CBZ-TR5190 also has two ultra-low-dropout linear regulators (ULDLRs) and two low-side switches. The ULDLRs operate in a linear mode to provide a low-ripple, low-noise power supply. The two low-side switches are used to control the current flow by turning the selected output channels on and off. This allows the user to optimize their design and power savings. The ULDLRs, the low-side switches, and the high-side switching channel can be controlled via an SPI or I2C interface and can be used to provide system power up/down sequencing, soft start, and system monitoring in an efficient manner.

The ISL6522CBZ-TR5190 is designed for a wide range of applications including automotive, industrial, and consumer electronics. It is a great solution for space-constrained designs that require efficient and reliable power management. The device\'s integrated features, flexible architecture, and adjustable parameters make it easy to customize the power supply for specific applications. As a result, the ISL6522CBZ-TR5190 is an ideal choice for designers looking for an integrated, reliable, and cost-effective DC-DC switching controller.
