IR3622MTRPBF is a monolithic, hybrid, non-synchronous DC-DC controller, which has a wide range of uses in power management. It is ideal for use in applications such as distributed power for high density and low cost point-of-load power systems. IR3622MTRPBF provides a high efficiency, low-cost solution for these power systems in a small package.

The IR3622MTRPBF can switch between two different regulated voltage levels, with no external parts required. As a DC-DC low side controller, it operates from an input range of 4.5 to 22V, and outputs a regulated voltage level up to 88V. The controller synchronizes to its own internally generated clock frequency of 160 KHz, which can be programmed via an external resistor. The IR3622MTRPBF’s internal overload protection and low RDS(ON) allows it to operate with a wide range of loads, up to 5A, which is ideal for providing accurate power distribution in a number of efficient, low-cost applications.

Typically, the IR3622MTRPBF DC-DC controller is used in distributed power systems to regulate voltages between a fixed voltage and between two different levels. It can be used to convert a higher input voltage from a power conversion module to a fixed low voltage level or between two different voltage levels, depending on the application. This controller can also be used in applications such as power management in routers, switches and other networking equipment.

The IR3622MTRPBF DC-DC controller uses its internal synchronous Boosted Flyback architecture, which combines both buck and flyback topology into a single circuit. It is designed to provide a defined regulated output voltage, while protecting itself and the system from any overvoltage or short circuit conditions. The controller uses the external MOSFETs to switch at a fixed frequency, while the internal synchronous architecture ensures high efficiency during both input and output conditions. The Boosted Flyback topology is ideal for applications that require scalability from low to high current range.

The IR3622MTRPBF’s high-side current sense feature also allows for advanced dynamic response, ensuring that output regulation is maintained during transient loads. The device supports a wide input voltage range, from 4.5V to 22V, and can provide a regulated output voltage up to 88V. The device also features a programmable soft start, which limits inrush current to the output stage, reducing the number of external components. An optional internal fast start also offers additional protection against output overvoltage.

The IR3622MTRPBF DC-DC controller is ideal for a wide range of applications, from low power to high current applications. Its high efficiency and small package make it an ideal solution for distributed power systems, providing accurate and reliable power distribution while reducing overall system costs. Its features make it the perfect choice for power management in routers, switches and other networking equipment, as well as inside consumer electronic devices, such as TVs, DVD players and audio systems.
