The LT1737IS#PBF is a high-performance, fast transient response, single output, current mode PWM controller designed by Linear Technology. This versatile controller is ideal for a wide range of power conversion applications, including isolated telecom power supplies, distributed power supply systems, and other portable and compact electronic devices.

Key Features

• Wide Input Voltage Range: The LT1737IS#PBF is capable of handling a broad input voltage range, which makes it suitable for various supply voltages.
• High Switching Frequency: With a switching frequency up to 500kHz, this controller allows the use of smaller external components, resulting in a more compact power supply design.
• Adjustable Soft-Start: The soft-start function prevents input current surge during startup, providing a smooth ramp-up of the output voltage to prevent stress on the power supply components.
• Current Mode Control: This feature provides excellent line and load transient response, and simplifies loop compensation.
• Power Good Output Voltage Monitor: This function provides a signal when the output voltage is within a specified range, which is useful for power sequencing and monitoring.
• Low Shutdown Current: The shutdown feature reduces the supply current to under 10µA, which is beneficial for power conservation in battery-powered applications.
