LTC3803ES6-3

LTC3803ES6-3 is a kind of constant frequency current mode flyback controller. It is designed for driving 6V-rated N-channel MOSFETs in high input voltage applications. It is available in a low profile (1mm) 6-lead SOT-23 (ThinSOTTM) package. The typical applications include telecom power supplies, 42 V and 12 V automotive power supplies, auxiliary/housekeeping power supplies and power over ethernetpowered devices.

There are some features of LTC3803ES6-3. (1)VIN and VOUT limited only by external components; (2)adjustable slope compensation; (3)internal soft-start; (4)-40 to 125 operating temperature range; (5)constant frequency 300 kHz operation; (6)±1.5% reference accuracy; (7)current mode operation for excellent line and load transient response; (8)no minimum load requirement; (9)low quiescent Current: 240A; (10)low profile (1mm) SOT-23 (ThinSOTTM) package.
