TPS62088A数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

The TPS6208xx device family is a high-frequency synchronous step-down converters optimized for small solution size and high efficiency. With an input voltage range of 2.4 V to 5.5 V, common battery technologies are supported. At medium to heavy loads, the converter operates in PWM mode and automatically enters power save mode operation at light load to maintain high efficiency over the entire load current range. The forced PWM version of the device maintains a CCM operation across any load. The 4-MHz switching frequency allows the device to use small external components. Together with its DCS-control architecture, excellent load transient performance, and output voltage regulation accuracy are achieved. Other features like overcurrent protection, thermal shutdown protection, active output discharge, and power good are built in. The device is available in a 6-pin WCSP package.
