Strengthening the link between the real and the digital worldTLD6098-1EP LITIX™ Power TLD6098-1EP is a DC-DC boost controller with spread spectrum frequency modulation and with built-in diagnosis and protection features especially designed for LED drivers.
LITIX™ Power TLD6098-1EP is a DC-DC boost controller with spread spectrum frequency modulation and with built-in diagnosis and protection features especially designed for LED drivers.
The TLD6098-1EP supports fixed current and fixed voltage output step-up/step-down configurations such as Boost, Buck, Buck-Boost, SEPIC and Flyback topologies.
The embedded spread spectrum modulator improves EMI performance. The device includes an integrated pulse width modulator to easily lower the LED brightness with reduced color shift. You also can modulate the output LED current using a digital pattern. TLD6098-1EP continuously monitors the load status: LED overcurrent, short to ground, overvoltage and overtemperature events are promptly indicated on a dedicated pin.
