Product Description
TPS61194PWPR Integrated Circuit Chip High-Performance 4-Channel LED Driver HTSSOP-20
The TPS61194PWPR is a high-efficiency, low-EMI, easy-to-use LED driver with flexibility to support a wide range of applications. It features four high-precision current sinks that can be combined for higher current capability.
Product Overview
This integrated circuit includes a DC-DC converter supporting both boost and SEPIC mode operation. The converter features adaptive output voltage control based on LED current sink headroom voltages, minimizing power consumption by adjusting voltage to the lowest sufficient level in all conditions. For EMI control, the DC-DC converter supports spread spectrum for switching frequency and external synchronization with a dedicated pin.
