STBB3JCCR Switching Regulator from STMicroelectronics

The STBB3JCCR is a highly efficient, dual-mode, synchronous switching regulator from STMicroelectronics, designed to deliver a constant output voltage with an impressive conversion efficiency. This advanced power solution is suitable for a variety of applications, including but not limited to consumer electronics, industrial systems, and portable devices, where energy efficiency and power density are critical.

At the heart of the STBB3JCCR lies a 2.1 MHz fixed-frequency PWM (Pulse Width Modulation) mode that ensures a compact solution with minimal external components. When operating in light-load conditions, the device seamlessly transitions to PFM (Pulse Frequency Modulation) mode, which significantly reduces the quiescent current, thus prolonging battery life in portable applications.

The STBB3JCCR is capable of delivering up to 3 A of continuous output current with an input voltage range of 2.5 V to 18 V, making it quite versatile for different power scenarios. The output voltage is adjustable from 1.2 V to 5.5 V, allowing for a wide range of uses across various electronic devices. The regulator's high switching frequency enables the use of small surface-mount inductors and capacitors, which reduces the overall footprint and allows for a more compact design in space-constrained applications.

For protection, the STBB3JCCR incorporates a comprehensive set of features, including overcurrent protection, thermal shutdown, and short-circuit protection. These features ensure the safe operation of the regulator and the protection of the end application from electrical mishaps. The device also includes an enable function that allows the power supply to be turned off, further reducing power consumption when not in use.

The STBB3JCCR is available in a VFQFPN 16L 3x3 mm package, which is designed to meet the requirements of a small form factor. This package is RoHS compliant and is designed for easy integration into a wide range of applications. With its robust design and advanced features, the STBB3JCCR from STMicroelectronics is an excellent choice for designers looking to improve the power efficiency and performance of their next project.
