The Linear Technology LM5117PMH/NOPB is a DC/DC buck-boost controller that can allow a three-terminal regulator to charge a flyback, boost or buck-boost converter. The built-in peak current mode architecture along with wide input voltage common-mode range allows for a robust, simplified and flexible design. The LM5117PMH/NOPB is designed to digitally control the output voltage of buck, boost and buck-boost switching converters.

The LM5117PMH/NOPB is an integrated buck-boost switching DC/DC regulator with PMBus1.2 interface, along with an adaptive io-zero compensation scheme and optimum frequency jitter system. The advanced current mode control offers excellent load transient response, and supports both wide input voltage common-mode and high voltage output operation. The built-in high side MOSFET is capable of driving up to 1.5A. Additionally, the device has an adjustable maximum duty cycle limit that prevents overshoot, and allows flexible current-limit profile settings. It also features 5V over-voltage protection and 5V under-voltage lockout.

The LM5117PMH/NOPB provides several features and benefits for its use in power management applications such as in automotive, medical and industrial systems. It is easy to program, allowing for a flexible control. In addition, it operates with high efficiency over a wide input and output voltage range, and it also features fast transient response, ripple control, and an internal bias current soft-start. The controller has a power-good indicator output, a disable input and selectable current limit for ease of use and reliable operation.

The LM5117PMH/NOPB is used in many power management applications such as battery management systems, charger systems, motor control circuits and voltage converters. It is also used in industrial systems, telecommunications, robotics, green architecture and other applications requiring efficient DC/DC power regulation.

The LM5117PMH/NOPB\'s working principle is based on peak current mode control. The device integrates an adaptive io-zero voltage compensation scheme, which measures the output voltage ripple and modulates the switching period accordingly. This provides fast transient response, and a high degree of system integration, allowing for small size designs. As well, the internal MOSFET has a peak current limit of 1.5A and adjustable frequency jitter, preventing unstable operation due to parasitic oscillations.

The LM5117PMH/NOPB is a powerful, high-efficiency and reliable DC/DC regulator that is designed to digitally control the output voltage of buck, boost and buck-boost switching converters. It provides excellent load transient response and supports both wide input voltage common-mode and high voltage output operation. The embedded adaptive io-zero compensation scheme and optimum frequency jitter system enable fast transient response, as well as high efficiency and small size. These features make the LM5117PMH/NOPB an attractive choice for use in power management applications.
