The TPS61325YFFT is a product of the Texas Instruments semiconductor device family and is primarily used as an LED driver. It is an instruction-driven power management integrated circuit (PMIC) that helps in controlling the output current of an LED light source.

It is commonly used within a battery powered application as it has low power consumption and can drive an up to two LEDs in an open-drain type configuration. An example use case would be a very efficient lighting solution for backlit displays.

This device consists of two standard buck boost regulators capable of operating in either step-up or step-down mode and can source or sink up to 25 volts. Both outputs have separate PWM controllers that control its output current and power levels. Additionally, the device has current monitoring feature, which helps ensure safe and reliable operation.

The device’s operation is based on four different modes. The first mode is the Over Voltage Protection (OVP) mode, which is designed to keep the output voltage above the design target level. The second mode is more basic and is the constant current mode, which is used to provide a constant current to the LED. The third mode is the standby mode, which is used to reduce power consumption when the LED is not in use. Finally, the fourth mode is the open loop mode, which is used to control the LED’s brightness.

The TPS61325YFFT is a great device for LED drivers due to its versatility, low power consumption and ease of implementation. It is suitable for battery-powered applications and can also be used in many other applications. This IC is becoming increasingly popular for its low cost and high performance.
