The LTC3803HS6-5 from Analog Devices is a constant frequency current mode flyback DC/DC controller designed for driving N-channel MOSFETs in high input voltage applications. It operates from input voltages as low as 5.7V up to 75V, making it suitable for a wide range of power supply designs.
This controller maintains constant frequency operation down to very light loads, minimizing low-frequency noise generation. Key electrical specifications include a 200kHz operating frequency, ±1.5% reference accuracy, and a low quiescent current of 240µA. It also features a 4.8V undervoltage lockout threshold.
The LTC3803HS6-5 is available in a compact 6-lead SOT-23 package, suitable for surface-mount applications. Its topology is Flyback, and it is designed for output power up to 15W. The operating temperature range is -40°C to 150°C.
This part is classified under Power Management ICs, specifically as a DC/DC Switching Controller. Its current mode operation ensures excellent line and load transient response. Slope compensation can be programmed with an external resistor, and it includes internal soft-start functionality.
