说明
- Typical Application Circuit for LT3755IUD-1 21W Buck-Boost Mode with 250:1 PWM Dimming and Open LED Protection. The LT3755-1 is a DC/DC controller designed to operate as a constant-current source for driving high current LEDs. It drives a low side external N-channel power MOSFET from an internal regulated 7.15V supply. The fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltages
