TL1464IPTR is a high-efficiency, low-dropout, low-voltage, dual-output Linear Regulator with an integrated 15A, 100V, N-Channel MOSFET. This device is geared towards applications that need to regulate a wide range of input and output voltages. It is suitable for battery chargers and other power management applications that require external FETs or low power operation.

Application Field

The TL1464IPTR is designed to provide a wide range of regulated output voltages from a single power supply. It can be used in a wide variety of applications, such as portable chargers, battery management systems, and automotive systems. Its low voltage dropout design allows it to be used in applications where the input voltage is close to the regulated output voltage.

The TL1464IPTR\'s high efficiency and low quiescent current make it an ideal choice for automotive systems. Its low quiescent current also makes it suitable for battery-powered applications that require a low power consumption. The adjustable output voltage allows the device to be used to regulate various output currents and voltages.

Working Principle

The TL1464IPTR is a current-mode Step-down Switching Controller. It operates by automatically selecting the most efficient mode of operation to regulate the output current or voltage. It features an internal comparator to monitor the output voltage and actuate a control signal, which is then processed by an internal logic circuit. The control signal is then sent to the MOSFET gate, which is connected to an external power supply.

The TL1464IPTR uses two feedback paths for the output voltage. A resistor divider provides feedback of the output voltage to the internal comparator. The other feedback path is provided by the output voltage sense resistor that is connected between the power ground and the output voltage pin. This allows the TL1464IPTR to measure the output voltage and to regulate the output voltage to a preset level. The feedback paths also provide over-voltage and under-voltage protection.

The TL1464IPTR also features a soft start function that helps to reduce inrush current during start-up. It also includes a thermal shut down function to reduce power dissipation in case of a fault. In addition, the TL1464IPTR includes a low battery detect pin that helps to protect the system from an over discharging battery.

The TL1464IPTR is an ideal solution for applications where wide input and output voltage ranges are required. Its high efficiency and low dropout make it well-suited for automotive systems and battery powered applications, and its adjustable output voltage allows for flexibility in voltage regulation.
