Working Principles

The TB62755FPG,EL is a high voltage, constant current sink driver specifically designed for driving LEDs. It operates by receiving serial data input through the DIN pin, which is then shifted into an internal shift register using the CLK (clock) signal. The data is then latched and transferred to the output channels when the STB (strobe) signal is activated.

Each output channel can sink a constant current, ensuring uniform brightness across connected LEDs. The device supports a wide input voltage range and can drive LEDs with voltages up to 40V. An output enable (OE) pin allows the device to enter a power-saving mode when not in use.

Detailed Application Field Plans

The TB62755FPG,EL is commonly used in various applications that require efficient LED driving. Some of the typical application fields include:

  1. LED displays and signage
