The TPS62933DRLR from Texas Instruments is a highly integrated, synchronous, step-down DC-DC converter designed for a broad range of applications. This Buck Switching Regulator IC is configured for a wide input voltage range of 3.8V to 30V and an output voltage range of 0.8V to 22V. This device features an ultra-low quiescent current of 12 µA, integrated 76-mΩ and 32-mΩ MOSFETs, and a 0.8 V ± 1% reference voltage at 25°C. It operates at a maximum duty cycle of 98% and has a precision EN threshold. The TPS62933DRLR supports a continuous output current of 3A and has an operating junction temperature range of –40°C to 150°C.
Key features of the TPS62933DRLR include its peak current control mode with internal compensation, allowing for a fast transient response and good line and load regulation without the need for external compensation components. It offers a selectable frequency range of 200 kHz to 2.2 MHz, which can optimize system efficiency, solution size, and bandwidth. The device also supports pulse frequency modulation for high light-load efficiency and forced continuous current modulation, which maintains lower output ripple during all load conditions. Additionally, it operates in out-of-audio mode to avoid audible noise and includes a frequency spread spectrum feature to help lower EMI noise.
The TPS62933DRLR is offered in a small SOT583 package (1.6 mm × 2.1 mm) with a 0.5-mm pin pitch, which is optimized for easy PCB layout and promotes good EMI performance. It includes cycle-by-cycle overcurrent protection for both high-side and low-side MOSFETs, as well as non-latched protections for OTP, OCP, OVP, UVP, and UVLO.
Applications for the TPS62933DRLR span across various fields where efficient power conversion is required, making it suitable for use in consumer electronics, industrial equipment, and automotive systems where high performance and reliability are paramount.
