The LTC3499EMS8#TRPBF is one of the voltage regulator offerings from the Power Management IC (PMIC) product line from Linear Technology Corporation. The LTC3499EMS8#TRPBF, a DC-DC switching regulator, is a power management IC designed with advanced features, such as side-by-side mounting, variable frequency operation, and up to 95% efficiency. The LTC3499EMS8#TRPBF is designed to reduce power consumption and increase power efficiency in various applications with its small size, low power consumption, and high power efficiency. It comes with adjustable current limiting, shut-down control, and thermal overload protection that can be used in both linear and switching regulator power supplies. It also has adjustable voltage output and can be utilized in applications that require high current with low input voltage, such as automotive, data communications, audio, telecom, and consumer electronic systems. The LTC3499EMS8#TRPBF is also ideal for applications using a wide range of input voltages, from 4.75 V to 130 V. It features integrated N-channel power MOSFETs with low on resistance. By using switching frequency from 200 kHz to 750 kHz, the device can achieve a high level of efficiency. The built-in low RDS(ON) power MOSFETs enable the output to be adjustable from 0.8 V to 10 V.The working principle of the LTC3499EMS8#TRPBF is fairly simple. It is a DC-DC switching converter with an N-channel MOSFET switch that uses switching to convert the input voltage to the desired output voltage. In each switching cycle, the switch is turned ON and OFF. When the switch is ON, charge is being transferred to the output. When it is OFF, the output is being discharged through the current path and clamped by the output capacitors. The switching frequency and ON time can be adjusted to optimize the load current and output voltage, resulting in improved efficiency and power quality. The LTC3499EMS8#TRPBF includes a type III "Overshoot Protection" circuitry that allows the device to achieve high performance in start-up and in the presence of heavy transient loads. This feature protects the system form current overshoot and helps provide reliable power. Additionally, the device comes with an integrated soft start that allows the output power supply to turn on slowly and gradually increase the output voltage. In summary, the LTC3499EMS8#TRPBF is a robust power management IC designed for DC-DC switching regulator applications. With its wide input voltage range, adjustable voltage output, high efficiency and integrated overshoot protection, the device is suitable for numerous high-performance systems.
