Buck Switching Regulator IC TPS563300DRLR Features
The TPS563300DRLR offers several key features that enhance its performance and reliability. It includes integrated high-side (76-mΩ) and low-side (32-mΩ) MOSFETs, reducing external component requirements. The device operates with a fixed 500kHz switching frequency and employs pulse frequency modulation (PFM) for high light-load efficiency. It features low quiescent current (20μA typical), which is ideal for battery-powered applications. Additionally, it provides comprehensive protection mechanisms, including over-temperature protection (OTP), over-voltage protection (OVP), under-voltage lockout (UVLO), and cycle-by-cycle over-current protection (OCP).
TPS563300DRLR Applications
The TPS563300DRLR is widely used in applications such as building automation, industrial PCs, multifunction printers, enterprise projectors, portable electronics, connected peripherals, smart speakers, and monitors. It is also suitable for distributed power systems with input voltages of 5V, 12V, 19V, and 24V.
Selecting the TPS563300DRLR offers several advantages. Its wide input voltage range and high output current capability make it adaptable to various power supply configurations. The device's low quiescent current and PFM mode maximize efficiency in light-load conditions, extending battery life in low-power applications. Its compact SOT583 package (1.6mm × 2.1mm) with optimized pinout simplifies PCB layout and reduces electromagnetic interference (EMI) through frequency spread spectrum technology. Additionally, its robust protection features ensure reliable operation in demanding environments.
