... Buck-Boost and SEPIC configuration with various load current levels by simply adjusting the external components. The TLD5095EL has a PWM output for dimming a LED load. The diagnostics are communicated on a status output (pin ST) to indicate a fault condition such as an LED open circuit. The switching frequency is adjustable in the range of 100 kHz to 500 kHz and can be synchronized to an external clock source. The TLD5095EL features an enable function reducing the shut-down current consumption to < ...

... Description The TLD5095EL has integrated circuits to diagnose and protect against output overvoltage, open load, open feedback and overtemperature faults. In case any of the four fault conditions occur the Status output ST will output an active logic low signal to communicate that a fault has occurred. During an overvoltage or open load condition the gate driver outputs SWO and PWMO will turn off ...
