Texas Instruments' TPS62088 devices are 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 4 MHz switching frequency allows TPS62088 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 over current protection, thermal shutdown protection, active output discharge, and power good are built-in. The devices are available in a 6-pin WCSP package.
