TLD60992SSEVALTOBO1

TLD60992SSEVALTOBO1 is a TLD6099-2ES dual-channel SEPIC topology evaluation board. This evaluation board embeds TLD6099-2ES, a multi-topology LED driver with Adaptive Output Discharge (AOD) feature. The board is designed to operate in SEPIC topology for both channels, that enables the user to regulate stable output current to a LED chain with a total forward voltage that can be lower, higher, or equal to the input voltage. The embedded AOD feature of the LED regulator TLD6099-2ES reduces the output current overshoot in case of fast load condition changes, such as transitioning the LED chain from 8 to 6 LEDs. Both channels are constantly monitored by the built-in diagnosis features of the TLD6099-2ES: short-to-ground, overvoltage on VFB pin, overvoltage on FBH pin and overtemperature.

• Diagnostic is always enabled to protect the load
• Output current overshoots are strongly limited from AOD functionality
• Input supply voltage range from 8 to 45V
• Output voltage range from 3 to 40V at max 13 white LEDs in series
• 1A output current range at SETn=100%
• 500kHz switching frequency at RFREQ=18kohm
• 0.8V maximum PWMI low voltage
• 2-60V PWMI high voltage
