Product Description
The LM5155QDSSRQ1 is a high-performance, switching controller IC designed by Texas Instruments for use in a variety of applications, including automotive systems. This IC is part of the LM5155 series and is designed to operate as a step-up or step-up/step-down DC-DC converter. It features a current-mode control technique with pulse-width modulation (PWM) and soft-start capabilities.
Product Features
Clock Synchronization: The LM5155QDSSRQ1 has a built-in clock synchronization feature, allowing it to operate in sync with an external clock signal.
Soft Start: The IC includes a soft-start feature, which helps to reduce inrush current and prevent voltage overshoot during startup.
Current-Mode Control: The LM5155QDSSRQ1 operates in current-mode control, which provides better regulation and stability compared to voltage-mode control.
Pulse Width Modulation: The IC uses PWM to regulate the output voltage, allowing for high efficiency and low noise.
Wide Operating Range: The LM5155QDSSRQ1 can operate with an input voltage range of 2.97V to 45V, making it suitable for a wide range of applications.
High Frequency Operation: The IC can operate at frequencies between 100kHz and 2.2MHz, allowing for high power density and compact designs.
Product Applications
Primary Applications: The LM5155QDSSRQ1 is suitable for use in automotive systems, such as engine control units, body control modules, and infotainment systems.
Secondary Applications: The IC can also be used in other applications, such as industrial power supplies, medical devices, and consumer electronics.
