The LTC3803ES6#PBF is a constant frequency, current mode flyback DC/DC controller from Linear Technology, optimized for driving N-channel MOSFETs in high input voltage applications. It maintains constant frequency operation down to very light loads, reducing low-frequency noise generation. This controller features a 200kHz operating frequency, ±1.5% reference accuracy, and current mode operation for excellent line and load transient response. It requires no minimum load and has a low quiescent current of 240μA.
The device is designed for high input voltage applications, with a maximum input voltage of 75V and a minimum input voltage of 9.2V. The output voltage can be as low as 0.8V. The switch current capability is up to 2A. The LTC3803ES6#PBF is packaged in a compact SOT-23 package, making it suitable for space-constrained designs. Its low profile (1mm) and small footprint are advantageous for miniaturized power supplies.
This controller is ideal for various power conversion applications requiring efficient and stable DC/DC regulation. Its features support robust performance across a wide range of load currents and input voltage variations. The flyback topology is commonly used for isolated power supplies.
