3 Description
The TPS60151 is a switched capacitor voltage
converter which produces a regulated, low noise, and
low-ripple output voltage of 5 V from an unregulated
input voltage. It maintains 5-V regulation even when
VIN is greater than 5 V.
The 5-V output can supply a minimum of 140-mA
current.
The TPS60151 has built-in current limit and output
reverse current protection that are ideal for HDMI,
USB OTG and other battery powered applications.
TPS60151 operates in skip mode when the load
current falls below 8 mA under typical condition. In
skip mode operation, quiescent current is reduced to
90 μA.
Only 3 external capacitors are needed to generate
the output voltage, thereby saving PCB space.
Inrush current is limited by the soft-start function
during power on and power transient states.
The TPS60151 operates over a free air temperature
range of –40°C to 85°C. The device is available with
a small 2-mm × 2-mm 6-pin SON package (QFN).
