TI公司的TPS54060 是60V 0.5A降压电源稳压器.它集成了200-m高边MOSFET,电流模式控制提供简单的外部补偿和灵活的元件选择,输入电压3.5V-60V,开关频率100kHz到2.5MHz,工作时的静态电流116uA,关断电流1.3uA,主要用在12-V, 24-V和48-V工业于商用低功耗系统,视频和GPS,娱乐设备等.本文介绍了TPS54060主要特性, 功能方框图, 带可调UVLO的高频3.3V输出等多种应用电路以及TPS54060EVM-590评估模块性能指标,电路图和材料清单.
The TPS54060 device is a 60V, 0.5A, 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, regulated output supply current to 116µA. Using the enable pin, shutdown supply current is reduced to 1.3µA, when the enable pin is low.
Under voltage lockout is internally set at 2.5V, but can be increased using the enable pin. The output voltage startup ramp is controlled by the slow start pin that can also be configured for sequencing/tracking. An open drain power good signal indicates the output is within 93% to 107% of its nominal voltage.
A wide switching frequency range allows efficiency and external component size to be optimized.
