... Boost Regulator 5.1 Description The TLD5098EL regulator is suitable for boost, buck-boost and SEPIC configurations. The constant output current is especially useful for light emitting diode (LED) applications. The regulator function is implemented by a pulse width modulated (PWM) current mode controller. The PWM current mode controller uses the peak current through the external power switch and error in the output current to determine the appropriate pulse width duty cycle (on time) for constant output current ...
