TPS82672SIPR

The Texas Instruments TPS82672SIPR is a 600mA, high-efficiency MicroSiP step-down converter module designed for power management applications. It operates with an input voltage range from 2.3V to 4.8V and provides a stable 1.5V output voltage. This module achieves up to 90% efficiency and features a low quiescent current of 17µA, making it suitable for power-sensitive designs.

Key electrical specifications include a switching frequency between 4.9MHz and 6.0MHz, a maximum duty cycle of 65%, and a typical switch current limit of 1.1A. The device offers features such as Enable, Light Load Efficiency, and Spread Spectrum for improved performance and reduced EMI. It also includes frequency dithering and integrated capacitors for noise reduction.

The TPS82672SIPR comes in a compact 8-uSIP package with dimensions of 3.0mm x 2.4mm x 1.0mm, designed for surface mount applications. Its operating temperature range is -40°C to 125°C. The module incorporates protection features like Overload Protection (OCP), Over-Temperature Protection (OTP), and Under-Voltage Lockout (UVLO) for enhanced reliability. The total DC voltage accuracy is within ±2%.

This converter module is suitable for ITE (Commercial) applications requiring efficient power conversion in a small form factor. Its design considerations include internal soft start, active power-down sequencing, and automatic PFM/PWM mode switching for optimal performance across various load conditions.
