The LTC3707IGN-SYNC-TRPBF is a high-frequency, high-voltage synchronous switching controller. It is designed to drive voltage-mode synchronous rectifiers in an isolated-flyback, semi- or full-bridge converters. It features four independent power outputs, programmable switching-freqeuncy synchronization and highly programmable PWM parameters. This controller is a great choice for applications that require precision voltage and current regulation.

This chip is specifically designed to reduce board area and power dissipation while providing high accuracy, reliability, and maximum flexibility along with high efficiency. It combines high frequency operation, programmable frequency synchronization, high efficiency and low cost into a compact design.

The LTC3707IGN-SYNC-TRPBF application fields include LED lighting, telecom power, medical, power tools and similar applications.

The working principle of the LTC3707IGN-SYNC-TRPBF is simple yet powerful. It features a proprietary Dual Mode™ architecture to provide a best-in-class, constant-switch frequency solution for isolated and non-isolated synchronous power converter designs. This architecture includes a 200ns minimum on-time constant-frequency PWM synchronous transistor driver, a latch-off comparator, fault detection, precision voltage reference, error amplifiers and optional external synchronization.

The controller operates in burst-mode® and pressure regulator modes to ensure wide load current range operation with the tightest possible voltage regulation. When operating in a pressure regulator mode, it offers a variable frequency output that adjusts automatically to the output load demand. This helps to ensure improved light load efficiency.

The LTC3707IGN-SYNC-TRPBF features a true zero load quiescent current, which reduces the overall system power consumption and increases energy efficiency. It also features three proportional current control loops with adjustable slew rate for smooth transitions and improved dynamic response. The output voltage is set by external resistors, and the current limit tolerance is programmable via external resistors.

The LTC3707IGN-SYNC-TRPBF is designed to meet the rigorous requirements of the most demanding applications. It features high efficiency, low EMI and low-voltage operation. It\'s also designed to provide the highest accuracy with simple loop compensation.

The LTC3707IGN-SYNC-TRPBF is a high-performance switching controller that offers designers maximum flexibility, low cost, and minimal board area. It is an ideal solution for a broad range of LED lighting, telecom power, medical, power tools and similar applications.
