Texas Instruments TPS54336ADDAR

The TPS5433xA family of devices are synchronous converters with an input-voltage range of 4.5 to 28 V. These devices include an integrated low-side switching FET that eliminates the need for an external diode which reduces component count.

Efficiency is maximized through the integrated 128-mΩ and 84-mΩ MOSFETs, low IQ and pulse skipping at light loads. Using the enable pin, the shutdown supply current is reduced to 2 μA. This step-down (buck) converter provides accurate regulation for a variety of loads with a well-regulated voltage reference that is 1.5% over temperature.

Cycle-by-cycle current limiting on the high-side MOSFET protects the TPS5433xA family of devices in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. A low-side sinking current-limit turns off the low-side MOSFET to prevent excessive reverse current. Hiccup protection is triggered if the overcurrent condition continues for longer than the preset time. Thermal shutdown disables the device when the die temperature exceeds the threshold and enables the device again after the built-in thermal hiccup time.

 

德克萨斯仪器tps54336addarthe tps5433xa系列器件具有4.5至28 V的输入电压范围内,这些设备同步转换器包括一个集成的低侧开关管,消除,减少了元件数量外部二极管的需要。

效率的最大化,通过综合128-mΩ和84-mΩMOSFET,低智商和脉冲跳跃在轻负载。使用使能引脚,关断电源电流降低到2 A A。这种降压(降压)转换器提供了精确的调节,对各种负载具有良好的调节电压参考,超过1.5%的温度。

逐周期电流限制在高侧MOSFET周期保护在过载情况下的设备tps5433xa家族是由一个低侧加电流限制以防止电流失控的增强。低侧限电流限制关闭低侧MOSFET,以防止过大的反向电流。如果过流状态持续时间超过预设时间,则触发打嗝保护。热关机禁用该设备时,模具温度超过阈值,使设备再次内置热打嗝时间后。
