The LT3748MPMS#TRPBF is a high voltage synchronous step-down switching regulator designed by Analog Devices. It is specifically designed to deliver high-power efficiency and robustness in industrial and automotive applications.
Key Features:
1. Wide Input Voltage Range: The LT3748MPMS#TRPBF can handle input voltages ranging from 4.5V to 100V. This wide input voltage range makes it suitable for a variety of power sources, including automotive batteries, industrial supplies, and other high voltage applications.
2. High Efficiency Operation: The regulator employs a synchronous step-down topology, which enables it to achieve high efficiency by reducing power dissipation. It employs low RDS(ON) (on resistance) MOSFET switches to minimize conduction losses, resulting in excellent overall power conversion efficiency.
3. Programmable Frequency: The IC allows flexible frequency programming with an external resistor or a clock input. This feature offers optimization for different operating conditions, providing designers the ability to select the best trade-off between efficiency and component size.
4. Burst Mode Operation: To maintain high efficiency under light load conditions, the LT3748MPMS#TRPBF incorporates a pulse-skipping mode known as Burst Mode operation. During low current operation, the regulator only draws minimal standby current, further reducing power consumption.
5. Fault Protection: The IC provides robust fault protection, including overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown
