The STP16CPC05XTTR is a part of the PMIC (Power Management Integrated Circuit) and LED (Light-Emitting Diode) drivers family from STMicroelectronics. This particular device is a monolithic high-brightness LED driver integrated circuit consisting of an array of 16 constant-current outputs with an internal PWM dimming controller. It is designed to drive arrays of single or multiple color, AC or DC LEDs in various applications such as Automotive and Industrial Lighting, Street Lighting, Smartphones, Signage and Decorative Lighting.

The STP16CPC05XTTR provides a wide range of features and benefits, such as a high voltage range of 9V to 32V, a low quiescent current, a programmable current from 5mA to 25mA and an onboard 16-bit PWM dimming engine. It also features an accurate current matched output with minimal ripple, a wide operating frequency range from 10 kHz to 7 MHz, adjustable current slew rate and a power shutdown function for superior thermal control and EMI performance.

The STP16CPC05XTTR’s working principle is based on a common sink current source driver architecture. The device contains 16 constant-current sources, one for each LED output. Each source is connected to a sink, which has the common connection to ground. The current of the LED output is controlled by a PWM signal. When the output is switched ON, the current source delivers current to the LED output. When the output is switched OFF, the current source is turned OFF, and the current stops flowing through the LED output.

The STP16CPC05XTTR is a versatile LED driver device, ideal for applications that need precise LED driving characteristics, such as those require smooth dimming, high frequency PWM, and multi-channel output. The device is also suitable for use in power supplies and battery-powered applications for improved efficiency. It is an ideal integrated solution for automotive and industrial lighting, as well as for decorative and signage lighting. The STP16CPC05XTTR provides a cost-effective and flexible solution for lighting applications that require high accuracy, reliability and efficiency.
