PMIC, or Power Management Integrated Circuits, are a type of integrated circuit that helps the circuit board to maintain regulator voltage and current. They are used to control, measure and regulate the power to specific components within a circuit. One of the specific applications that PMICs are often used for is laser drivers. And TZA3011AVH/C2,557 is an example of such a PMIC.

TZA3011AVH/C2,557 is a highly integrated PMIC specifically designed to power laser diodes. It utilizes voltage-mode control to ensure reliable and robust current regulation, offering external-input control up to a maximum 4A output current. It uses a full bridge switch controller with a differential amplifier for the feedback loop, providing excellent line and load regulation, as well as fast response on output current changes. The full bridge switch works by alternately switching the output current each phase, leading to a higher efficiency than the other, typical buck-mode converter solutions.

TZA3011AVH/C2,557 offers great flexibility in terms of the driver’s capabilities. It supports a wide range of output voltages and current options, and it can be operated in both pulse voltage and pulse current mode. The power supply range is 4.5V to 25V, and the output current can be set up to a maximum of 4A. The main advantage of using this power supply is the low ripple and noise levels. This ensures the stability and reliability of the laser diode, while the low EMI ensures that the laser beam does not degrade.

The TZA3011AVH/C2,557 also features an Integrated Thermal Protection (ITP) system, which helps to protect the driver from overheating by shutting off the output current. Overheating can cause permanent damage to the driver, so preventing it is of utmost importance. Additionally, this PMIC also supports pulse-by-pulse current limiting and soft-start, a feature common among PMICs that helps to reduce inrush current and eliminate any startup transients.

TZA3011AVH/C2,557 is an excellent example of a powerful and reliable PMIC laser driver. It is capable of driving laser diodes, LEDs, and other similar lighting devices with ease and stability. Its wide input and output range and additional safety and protection features make it a great choice for the most demanding of applications. With its reliable current regulation and low ripple and noise levels, this PMIC laser driver is sure to be of great value in any laser diode application.
