Unisonic Technologies UD05208
the UD05208 automatically enter into Power Save Mode at the lowest quiescent current (50μA typ) to maintain high efficiency over the entire load current range. The UD05208 provide an adjustable output voltage via an external resistor divider. The output voltage start-up ramp is controlled by an internal soft start, typically 250 μs.| Part No. | UD05208 |

DESCRIPTION
UTC UD05208 devices are synchronous step-down converters optimized for small solution size and high efficiency. The devices integrate switches capable of delivering an output current up to 2A. The devices are based on an adaptive on time with valley current mode control scheme. Typical operating frequency is 1.5MHz at medium to heavy loads. The devices are optimized to achieve very low output voltage ripple even with small external components and feature an excellent load transient response. During a light load, In shutdown, the current consumption is reduced to 1μA. Power sequencing is possible by configuring the Enable pin. Other features like over current protection and over temperature protection are built in.●
