Introduction

AI Translation

The TPS61194 is a high - efficiency, low - EMI, easy - to - use LED driver that can flexibly support various applications. This device features four high - precision current sinks, which can be used in combination to increase the current capability. The integrated DC/DC converter in the TPS61194 supports boost and SEPIC operating modes. This converter can provide adaptive output voltage control based on the headroom voltage of the LED current sinks. This feature can regulate the voltage to the lowest level that meets the requirements under all conditions, thereby minimizing power consumption. To achieve EMI control, the DC/DC converter supports spread - spectrum modulation for the switching frequency and external synchronization using a dedicated pin. The TPS61194 has a wide input voltage range of 4.5V to 40V, providing reliable support for a variety of different applications. The TPS61194 integrates a rich set of fault detection functions. For a 100Hz input PWM frequency, the device supports a PWM brightness adjustment ratio of 10000:1.
