LINEAR TECHNOLOGY DC1319B-A 工具套装
LINEAR TECHNOLOGY DC1319B-A EVALUATION BOARD, LT3756 500mA LED DRIVER
LINEAR TECHNOLOGY
DC1319B-A demo board features a high voltage and high current LED driver controller LT3756-2. The input voltage is as high as 100V, and LED output voltage is also as high as 100V. The demo circuit is assembled as a boost topology from 8V to 80V input and up to 80V LED output at 0.5A with an open LED status pin. DC1319B features PWM dimming, analog dimming, shutdown, and open LED overvoltage protection. Efficiency at 12VIN is as high as 91% for 40W output. The switching frequency is set at 300KHz to accommodate the automotive switching frequency range. The open LED overvoltage protection limits the output to approximately 92V if the LED string is opened. DC1319B PWM dimming is simple. The boost topology LED string returns to the LED terminal and the PWM dimming MOSFET turns the LED string on and off with an input to the PWM dimming terminal. Soft start is provided with a simple and small capacitor to maintain control of the switch current during turn on for high power designs. 3000:1 true colour PWM dimming Constant current and constant voltage regulation High side current sense Drives LEDs in boost topology Open LED protection, low shutdown current Programmable undervoltage lockout with hysteresis Improved open LED status pin PWM disconnect switch driver CTRL pin provides analog dimming Programmable softstart Core Chip: LT3756-1, LT3756-2 Device Topology: Boost (Step Up) No. of Outputs: 1Outputs Output Current: 500mA Output Voltage: 80V Input Voltage Min: 8V Input Voltage Max: 80V Dimming Control Type: PWM Kit Contents: Evaluation Board for LT3756 Product Range: - SVHC: No SVHC (17-Dec-2015) Find similar products grouped by common attribute
