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 component count.
