LTC1735IS#TRPBF

The LTC1735IS#TRPBF is a high-performance, high-efficiency DC-DC switching controller IC from the family of PMIC - Voltage Regulators - DC DC Switching Controllers. The IC utilizes a mixed-mode control architecture which combines traditional PWM with low-power switching, allowing for high efficiency and reliable operation. It also has integrated switching protection, making it suitable for many applications.

The LTC1735IS#TRPBF is well-suited for a wide range of applications, such as multi-output DC-DC power supplies, tabletop power supplies, portable power supplies, switching supplies for datacenter and industrial applications, and adaptive charging systems. It is designed to be used as a controller for buck and boost regulated DC-DC converters, and can be used as a stand-alone controller with just a few external components.

The device\'s output current is not limited by a current sense resistor. Rather, current sensing is done through comparison of the drain to source voltages of the output switch against an internally generated voltage. This allows for very precise current setting and eliminates the need for external shunt components. The device’s switch current is determined by the slope of the inductor current and the output voltage, which is adjustable using an external voltage divider.

The LTC1735IS#TRPBF also integrates MOSFET gate drivers, which provide fast transitions and low power use. Its droop control helps provide a stable output voltage, even under high transient loads. The device also features protection against over-voltage and over current situations. Additionally, the IC features a 15-bit clock synchronization feature which helps synchronize the device with a master clock, improving efficiency and making it suitable for synchronous rectification applications.

The LTC1735IS#TRPBF also integrates various power management functions, allowing for an optimized power supply design. It supports inrush current control and has an adjustable soft start time. It also includes power fail detect and power good signals, which allow the designer to detect whether the power supply is within regulation requirements and to take corrective action as necessary.

Overall, the LTC1735IS#TRPBF is an excellent solution for DC-DC switching applications such as multi-output DC-DC power supplies and desktop power supplies. Its combination of high performance, high efficiency, and low power use make it an ideal choice for a wide range of applications.
