Overview
| Topology | Boost Converter |
| Input voltage | 9-18 V |
| Output 1 | 57 V / 0.12 A |
Description
Demonstration circuit 2630A is an I2C programmable quad channel monolithic boost LED driver featuring the LT®3966. It drives four separate strings of LEDs (up to 50V) at 125mA when VIN is between 9V and 18V. DC2630A runs at 2MHz switching frequency. Its four channels are capable of powering LED strings which can have different currents, voltages, or dimming ratios. Each channel can be independently controlled via I2C communications or analog inputs. DC2630A can be configured to run in either mode by modifying the ADDR pin settings. It is protected against output overcurrent, overvoltage events, and reports open and short LED fault events by latching an alert pin. In I2C mode, faults can be enabled or disabled. A DC2026C Linduino® One demonstration circuit is used to interface with the board by directly connecting it with a QuikEval™ ribbon cable and provided command line interface code.
Features
The LT3966 has an input voltage range from 3V to 60V.Each boost channel has an integrated 60V 1.6A low-side power switch. It has adjustable switching frequency between 300kHz and 2MHz and can be synchronized to an external clock source. Additionally, LT3966 can be programmed to output its own master clock to sync other devices. The high side PWMTG MOSFET drivers assist with PWM dimming and fault protection. The LT3966 channels can be configured to operate as a ground-referenced step-up (boost) LED driver, or as a floating output LED driver to perform step-down (buck mode) or step-up/step-down (buck-boost mode) operation.
