SLVSCD1C – DECEMBER 2013 – REVISED NOVEMBER 2015 TPS92561 Phase-Dimmable, Single-Stage Boost Controller for LED Lighting
1 Features 3 Description 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. 1 Simple Hysteretic Control
