TPS54160QDGQRQ1

TEXAS INSTRUMENTS  TPS54160QDGQRQ1  直流-直流开关降压, 逐步递降稳压器, 可调, 3.5V-60V输入, 1.5A输出, 2.5MHz, MSOP-10

The is a Step-down Regulator with an integrated high-side MOSFET. Current-mode control provides simple external compensation and flexible component selection. A low-ripple pulse-skip mode reduces the no-load, input supply current to 116µA. Using the enable pin reduces the shutdown supply current to 1.3µA. Undervoltage lockout is set internally at 2.5V but can be increased using the enable pin. The slow-start pin, which is also configurable for sequencing or tracking, controls the output-voltage start-up ramp. An open-drain power-good signal indicates the output is within 92 to 109% of its nominal voltage. A wide switching-frequency range allows optimization of efficiency and external component size. Frequency foldback and thermal shutdown protect the part during an overload condition.
