概述

The TPP21206 is a high-efficiency, easy-to-use, fully integrated synchronous step-down regulator with 2.7-V to 16-V wide input voltage range and 12-A continuous output current capability. One internal LDO is integrated for a compact single-input power supply. A wide range of external VCC bias from 3 V to 5 V can replace the internal LDO to further enhance the efficiency of the system.

The TPP21206 adopts fast transient response, constanton-time control with fixed frequency function over different duty cycle and load current range. Differential remote sense feedback with 1% accuracy reference voltage over the full operating temperature range ensures excellent output accuracy and regulation. The high-integrated compensation provides a stable control loop with zero ESR output capacitors, supporting flexible component selection and easy-control stability.

The device features adjustable and accurate current limits for both high-side, low-side positive, and low-side negative current limit to ensure safety. The open-drain PWRGD with active clamped output can enhance the supply reliability during system malfunction. The device has builtin protection and diagnostic features such as cycle-bycycle current limit, under-voltage protection, over-voltage protection, UVLO, and over-temperature protection.
