ISL8104CBZ is an integrated voltage regulator and switching controller designed to drive an external N-Channel MOSFET in power converters and power supplies. The controller is high performance and highly efficient, offering an integrated solution for a wide range of applications including synchronous and non-synchronous buck, buck-boost, and flyback DC-DC converters. The device is also suitable for single-end forward converters, battery chargers, and phase-shifted forward converters. The ISL8104CBZ can be used with a wide range of input and output voltages, making it an ideal solution for the wide stepping range of many applications. The ISL8104CBZ has an integrated voltage regulator and current mode PWM controller for operating with external NMOS and PMOS external transistor sets. The voltage regulator includes an error amplifier, voltage reference/monitor, and an Adjustable Precision Oscillator (APO). The current mode PWM controller includes an Oscillator and Ramp Generator, Comparator, and an inhibiting deadband. The ISL8104CBZ features a wide operating temperature range and low output voltage noise, making it perfect for use in space-constrained applications. It also has an over-voltage protection (OVP) to prevent the drain voltage of the external NMOS transistor set from exceeding an adjustable threshold. The device also features a dedicated sleep mode, which allows the user to place the device in a low-power mode for system power savings. The ISL8104CBZ also has an input voltage range from 8.5V to 18V and an adjustable output voltage range of 0.5V to 5.5V. The device can be used in single-ended applications, with a minimum input voltage of 2V and a maximum of 18V. The output voltage can be set as needed to meet the output voltage requirements of the application.The ISL8104CBZ has a flexible and powerful control interface, which includes analog control and digital control. The analog control is user-selectable, allowing the user to adjust the switching frequency and deadtime for optimum performance. For digital control, the ISL8104CBZ provides a high-speed SPI (Serial Peripheral Interface) interface for communicating with external microcontrollers and other system components. The ISL8104CBZ is designed for minimal external external components, reducing cost and improving reliability. The device also has integrated protection functions, including thermal shutdown and soft-start. The output can be protected from over-voltage, under-voltage, and over-current conditions and the device also has an adjustable short-circuit protection timer to provide additional system protection. Overall, the ISL8104CBZ is an ideal solution for a wide range of DC-DC converter applications and provides an integrated, low-cost, and low-noise solution. Its high efficiency, wide temperature range, low-noise operation, and integrated protection features make it an excellent choice for a wide range of applications.
