DC2788A Demonstration Circuit for LT3950
Analog Devices DC2788A Demonstration Circuit for LT®3950 is a lift LED driving force featuring the LT3950. This demonstration circuit powers a string of LEDs at 330mA. The step-up topology may be used to power a string of up to 28V LEDs as assembled. The maximum output voltage functionality of the LT3950 is 60V. DC2788A runs from an enter voltage variety of 6V to 24V as built. It additionally runs at 2MHz and may turn on spread spectrum frequency modulation (SSFM) for a frequency range of 2.0MHz to 2.5MHz. Dimming manipulate may be achieved with analog dimming or PWM dimming—either from an outside or internally-generated clock source. DC2788A capabilities an undervoltage lockout (UVLO) set at 6.6V with a 1.0V hysteresis for flip-on. The UVLO voltage, LED modern, output voltage variety, switching frequency, brightness control, SSFM, and the topology can all be adjusted with easy adjustments to the demonstration circuit.
