LED Drivers

The STOOPF221A5Z032S00 is a LED driver designed for high power LED applications. It is a switch-mode constant current driver capable of driving up to 32 LEDs connected in series. It is an integrated circuit that can be used to regulate the current that drives a LED, allowing it to be operated at a wide range of current levels and with a variety of control options.

The STOOPF221A5Z032S00 is intended for driving linear LED strings in LCD TVs, LED backlight modules, LED lighting and other applications that require a consistent amount of current being sent to the LEDs.

It has been designed to minimize size and power consumption, making it suitable for small form-factor applications. It is also designed to be easy to use, allowing it to be integrated into a wide range of end products.

The STOOPF221A5Z032S00 features a wide input voltage range (8~80 VDC), making it suitable for applications that operate from a wide array of power sources.

The STOOPF221A5Z032S00 uses a pulse width modulation (PWM) control signal to regulate the output current. PWM works by switching the output current on and off at a certain frequency, and the duty cycle of the signal is what determines the output current. This allows for precise current regulation over a wide range of output currents.

It also includes over voltage protection and over temperature protection to ensure the safety of the LEDs. It also includes a typically low current shutoff feature, allowing it to reduce power consumption when not in use.

In addition, the STOOPF221A5Z032S00 features a built-in thermal foldback protection circuit that can be used to prevent the driver from overheating. This feature is especially important in applications with high input voltages, where the power dissipation can be much higher than in applications running at a lower voltage.

The STOOPF221A5Z032S00 is capable of driving up to 32 LEDs connected in series. The output current is adjustable over a wide range, allowing it to be used in a wide variety of LED applications.

Overall, the STOOPF221A5Z032S00 is a versatile and easy-to-use LED driver that can be used in a variety of applications. Its small size, wide input voltage range, and power-saving features make it ideally suited for use in LCD TVs, LED backlight modules, LED lighting and other applications.
