TPS54360DDA

TEXAS INSTRUMENTS  TPS54360DDA  直流-直流开关降压逐步递减稳压器, 可调, 4.5V-60V输入, 800mV-58.8V输出, 3.5A输出, SOIC-8

The is a step-down Voltage Regulator with an integrated high side MOSFET. The device survives load dump pulses up to 65V per ISO 7637. Current mode control provides simple external compensation and flexible component selection. A low ripple pulse skip mode reduces the no load supply current to 146µA. Shutdown supply current is reduced to 2µA when the enable pin is pulled low. Under-voltage lockout is internally set at 4.3V but can be increased using the enable pin. The output voltage start up ramp is internally controlled to provide a controlled start up and eliminate overshoot. A wide switching frequency range allows either efficiency or external component size to be optimized. Frequency fold-back and thermal shutdown protects internal and external components during an overload condition.
