TPS54060MDGQTEP

TPS54060 器件是一款带有集成型高侧MOSFET 的60V，0.5A，降压稳压器。它采用电流模式控制，可实现简单的外部补偿和灵活的组件选择。其低纹波脉冲跳跃模式可将无负载的稳压输出电源电流减小至116μA。通过使用使能引脚，在该引脚为低电平时，关断电源电流将降至1.3μA。

其欠压锁定电压在内部设定为2.5V，但可用使能引脚将之提高。输出电压启动斜坡受控于慢启动引脚，还可以配置该引脚来控制排序/跟踪。开漏电源状态良好信号表示输出处于其标称电压的93%至107%之内。

宽开关频率范围允许对效率及外部组件尺寸进行优化。频率折返和热关断功能在过载情况下保护部件。

TPS54060 采用10 引脚散热增强型MSOP10 PowerPAD 封装。

The TPS54060 device is a 60-V, 0.5-A, step-down (buck) regulator with an integrated high-side N-channel MOSFET. To improve performance during line and load transients, the device implements a constant frequency, current mode control, which reduces output capacitance and simplifies external frequency compensation design. The wide switching frequency of 100 to 2500 kHz allows for efficiency and size optimization when selecting the output filter components. The switching frequency is adjusted using a resistor to ground on the RT/CLK pin. The device has an internal phase lock loop (PLL) on the RT/CLK pin that is used to synchronize the power switch turn on to a falling edge of an external system clock.

The TPS54060 has a default start-up voltage of approximately 2.5 V. The EN pin has an internal pullup current source that can be used to adjust the input voltage UVLO threshold with two external resistors. In addition, the pullup current provides a default condition. When the EN pin is floating, the device will operate. The operating current is 116 μA when not switching and under no load. When the device is disabled, the supply current is 1.3 μA.

The integrated 200 mΩ high-side MOSFET allows for high-efficiency power supply designs capable of delivering 0.5 A of continuous current to a load. The TPS54060 reduces the external component count by integrating the boot recharge diode. The bias voltage for the integrated high-side MOSFET is supplied by a capacitor on the BOOT to PH pin. The boot capacitor voltage is monitored by an UVLO circuit and will turn the high-side MOSFET off when the boot voltage falls below a preset threshold. The TPS54060 can operate at high duty cycles because of the boot UVLO.
