LM5176PWPT Integrated Circuits (ICs)

The LM5176PWPT is an integrated power converter that consists of a PWM controller, two power switches, integrated logic and protection, and a wide range of pin-out options. It is designed for robust, efficient, and fast transient response, making it ideal for highly dynamic applications. It is a versatile, multi-mode device that is capable of working in fixed frequency, automatic synchronization mode, or voltage mode to improve system efficiency in a number of different applications.

The LM5176PWPT is part of the LM500 family of monolithic power converters. It is designed to provide an ultra-low-voltage and power efficient solution for power supplies and other power conversion applications. The application field includes a variety of products from consumer electronics, automotive, and industrial to telecom, computing, and medical.

The LM5176PWPT belongs to the PMIC - Voltage Regulators - DC DC Switching Controllers category. As a member of the LM500 family, it contains four primary blocks, including the PWM controller, power devices, protection and logic, and an internal resistor ladder.

The PWM controller implements both the pulse width modulation signal and the over voltage protection. It combines high frequency oscillator and restive divider to generate the feedback voltage sense. In addition, the PWM Controller also has the ability to operate in either voltage or frequency mode.

The power devices include two power MOSFET switches for active switching. The features of the power switch includes a high-current body diode and a low quiescent current. The protection and logic includes a multi-mode over voltage protection circuit, an over temperature protection circuit, an under voltage lockout circuit, a soft-start feature, and a user-programmable frequency (placed in either PWM or frequency mode).

The internal resistor ladder provides accurate reference voltages for the PWM bias voltage, over voltage protection circuit, temperature protection, and the under voltage lockout circuit. The input of the resistor ladder can be connected to either the low voltage side or the high voltage side of the power switches.

The LM5176PWPT is designed to support a wide range of input and output voltages, operating temperature ranges, and current levels. Its operating temperature is from -40°C to 125°C, and it includes auto-cycle skip, pulse-skip, and burst-mode operation. The LM5176PWPT also provides a built-in soft start, external synchronization for paralleling multiple supplies, and over-voltage protection. This device has a high power efficiency and a low standby current, making it ideal for energy-sensitive applications.

Overall, the LM5176PWPT is a robust, efficient, and fast transient response controller that is suitable for a range of applications. It is an integrated power converter that combines PWM controller, two power switches, logic and protection, and a wide range of pin-out options, making is a versatile, multi-mode device to improve efficiency in applications.
