The TPS92561 device is a boost controller for LED lighting applications utilizing
high-voltage, low-current LEDs. A boost converter approach to lighting applications allows the
creation of the smallest volume converter possible and enables high efficiencies beyond 90%. The
device incorporates a current sense comparator with a fixed offset enabling a simple hysteretic
control scheme free of the loop compensation issues typically associated with a boost converter.
The integrated OVP and VCC regulator further simplify the design procedure and reduce external
