APPLICATION INFORMATION
TRANSIENT VOLTAGE PROTECTION
One of the primary applications of the TPS7A4101 is to provide transient voltage protection to sensitive circuitry
that may be damaged in the presence of high-voltage spikes.
This transient voltage protection can be more cost-effective and compact compared to topologies that use a
transient voltage suppression (TVS) block.
LED ARRAY DRIVER
The TPS7A4101 can be used to drive several LED drivers connected in series, as shown in Figure 13.
Figure 13. LED Array Driver Application
The TPS7A4101 high voltage rating makes it suitable not only for driving the intensity of an array of multiple
LEDs by using a PWM signal at its EN pin, but also for controlling such an array. This PWM signal enables and
disables the regulator, causing the LED light to vary its intensity.
