THL3512-B is a PMIC - LED Drivers used for driving white LEDs. It converts a DC voltage supply into a constant current to power a linear array of white or warm LEDs, thereby providing efficient, controlled illumination. The current flow through the LEDs is controlled with a PWM signal, allowing the user to vary the LED brightness while maintaining the same current level.

The THL3512-B is an efficient, cost effective LED driver, which operates using pulse-width modulation (PWM) control. The device is an integrated solution, providing constant current to drive a linear array of white or warm LEDs, while allowing the user to vary the LED brightness with a PWM signal. The device operates efficiently over a wide range of input voltage, from 4.5V to 40V. It also has an internal soft start circuit and over temperature protection.

The THL3512-B application field is focused on Outdoor Lighting, Signal lighting and residential lighting projects. Applications include street lighting, Security lighting, Parking lot lighting, Tunnel lighting and billboard lighting.

The main features of THL3512-B include:

• Wide Input Voltage Range – 4.5V  to 40V
• Constant Current
• PWM Control
• Internal soft start
• Over temperature protection

The working principle of the THL3512-B is as follows: The device contains a Buck boost PWM switch, an oscillator and a control circuit. The internal control circuit monitors the voltage feedback from the LED string and the input voltage. Depending on those two signals, the switch is opened and closed periodically through the oscillator. The duty cycle of the switch is used to adjust the output current and to maintain the voltage across the LEDs constant. The PWM signal is used to vary the current and brightness of the LEDs.

In summary, THL3512-B is an efficient, cost effective PMIC - LED Drivers used for driving white or warm LEDs in an array form. It works using pulse width modulation and provides an adjustable output current with a wide input voltage range. It is ideal for applications such as street lighting, security lighting, parking lot lighting, tunnel lighting and billboard lighting.
