The LT1573CS8#TRPBF is a programmable high-current monolithic switching regulator controller IC from Linear Technology that is optimized for the control of buck switching regulators. Its features make it an ideal choice for applications in the field of industrial equipment, power management, and power measurement.

The LT1573CS8#TRPBF is a low-power consumption controller, allowing it to operate efficiently in a wide range of voltage and current applications. It is designed to support output voltages of up to 20V and output currents of up to 5A with a switching frequency up to 2MHz. The low-power consumption operation is achieved through the use of a PWM under-voltage protected power stage and a current mode control loop.

The LT1573CS8#TRPBF provides excellent transient response and power supply rejection allowing it to remain stable in the presence of line, load and temperature variations. The oscillator and comparator of the controller automatically adjust the switching frequency and duty cycle as necessary for a more accurate output voltage and current. Additionally, the Overtemp Shutdown and Overcurrent protection features help protect the device and system from damage due to overheat or overcurrent conditions.

The LT1573CS8#TRPBF features built-in precision voltage and current comparators, voltage feedback, and current feedback for improved system performance and accuracy. An external resistor and capacitor network is used to program the operating frequency, the current sense threshold, the output voltage sense curve, etc. Additionally the device provides differential voltage output logic pins for the control of an external low-side switch, which can be used to reduce the turnon/turnoff time or current ripple at the output voltage.

The LT1573CS8#TRPBF is an ideal solution for applications in industrial equipment, power measurement, and power management. It is designed to operate with low power consumption, support output voltages of up to 20V and output currents of up to 5A with a switching frequency up to 2MHz, and provide improved system performance and accuracy. It also features built-in protection features such as an Overtemp Shutdown and an Overcurrent protection, as well as differential voltage output logic pins for the control of an external low-side switch. With its low-power consumption, accurate regulation, and great protection features, the LT1573CS8#TRPBF is an excellent choice for linear regulator controller applications.
