Product Overview
LTC3803-5 is a constant frequency current mode flyback controller optimized for driving N-channel MOSFETs in high input voltage applications. It operates from inputs as low as 5V. Constant frequency operation is maintained down to very light loads, resulting in less low frequency noise generation over a wide range of load currents. Slope compensation can be programmed with an external resistor. Ground referenced current sensing allows device-based converters to accept input supplies beyond the device’s absolute maximum VCC. For simplicity, this device can be powered from a high VIN through a resistor, due to its internal shunt regulator. An internal undervoltage lockout shuts down the IC when the input voltage is too low to provide sufficient gate drive to the external MOSFET. It is widely used in applications such as 42V and 12V automotive power supplies, telecom power supplies, auxiliary/housekeeping power supplies, power over ethernet etc.
- VIN and VOUT limited only by external components
- VCC turn on voltage is 4.8V typical at (TA = 25°C, VCC = 5V)
- Adjustable slope compensation
- Internal soft-start, no minimum load requirement
- ±1.5% reference accuracy
- Current mode operation for excellent line and load transient response
- Low quiescent current is 240μA typical at (VITH/RUN = 1.3V, TA = 25°C, VCC = 5V)
- Soft-start time is 0.7ms typical at (TA = 25°C, VCC = 5V)
- Operating junction temperature is -40°C to 125°C
- Package style is 6-lead SOT-23
