The STP16CPPS05PTR is a serial programmable constant current LED sink driver that is primarily used for LED display applications. It is an integrated circuit with a monolithic power supply containing an oscillator controller, power transistor, and power diodes. The STP16CPS is widely used in LED TVs, LED signs, LED display units, LED bulbs, LED lighting and other lighting applications.

The STP16CPPS05PTR can be controlled by serial data input (SPI/I2C) and current setting voltage. The user can choose between 8~320mA current levels. It contains 16 constant current sink outputs, and each output will output current equal to or close to the selected constant current value. It can work at a wide range of voltage from 3V to 11V. The device is offered in an 8-pin TSSOP package. Other features include under-voltage lockout, thermal shutdown, and peak current limiting.

The working principle of the STP16CPPS05PTR is as follows. First, an incoming pulse width modulated (PWM) signal is used to control the sink current. The PWM pulses are provided to the input of the internal oscillator users can select various current levels in response to the incoming pulses from the PWM interface. When the sink current exceeds the under-voltage lockout (UVLO) threshold, the device will enable the sink current. When the current value reaches the set current level, the device will switch off the transistor and keeps the current within a close range. The thermal shutdown (TSD) and peak current limiting (PCL) are safety features of the device to ensure the device does not get damaged and to protect the LED from damages.

The STP16CPPS05PTR is a very efficient and reliable device for LED display applications. The device integrates an oscillator and a power transistor which efficiently drives and controls the LED display. The device is suitable for a wide range of supply voltage, allowing design versatility. The PWM input, with 8-320 mA current selection, offers a flexible selection of LED brightness levels. This reduces the number of components in the system and improves system efficiency. The device also incorporates important safety features such as UVLO, TSD and PCL, to ensure safe and reliable operation.
